TCI Steroids
Steroids are compounds consistuted of four fused rings, for example, the most common and best known steroid in humans, cholesterol. In animals, steroids are biosynthesized from lanosterol and are widely distributed. The distinctive feature in steroids is lack of methyl group at C-4 position as compared to terpenes. In this section, we have classified steroids into five basic categories based upon their chemical composition.
Estrogens:
Estrogens function as the primary female sex hormone and in combination with synthetic progestogens can be used as oral contraceptives to suppress ovulation. Recently, it is also reported that they are effective for the prevention of osteoporosis, heart attacks and Alzheimer’s disease in women.
Androgens:
Testosterone is not only the principal and most well known male sex hormone but is also known to exert anabolic effects. This is also the main reason why some of them have been banned from use as bone density enhancers and musclebuilding drugs by several sports organizations. They are also the intermediates of estrogene biosynthetic pathway or rather the precursors of all estrogens.
Progestogens:
The only naturally occuring progestogen, i.e., progesterone, exhibits antiovulatory action. Based on its structure, derivatives of 19-nortestosterone were synthesized and can be used as oral contraceptives.
Corticoids:
Synthetic corticoids such as dexamethasone and prednisolone find clinical use as anti-inflammatory agents. They are synthetically developed based on the structure of cortisone, a natural corticoid.
Initiators are often used in chain-growth polymerization such as radical polymerization to regulate initiation by heat or light.
Thermal polymerization initiators are compounds that generate radicals or cations upon exposure to heat. For example, azo compounds such as 2,2'-azobis(isobutyronitrile) (AIBN) and organic peroxides such as benzoyl peroxide (BPO) are well-known thermal radical initiators, and benzenesulfonic acid esters and alkylsulfonium salts have been developed as thermal cation initiators.
Photopolymerization initiators are used in many fields to generate photocurable composites. These composites are polymerized by irradiation with UV light and electron beam which leads to altered physical properties of the composites such as solubility, viscosity and adhesiveness. In particular, the phenomenon in which a liquid changes into a solid is most useful and is applied to surface-treating techniques in fields including paints, printing inks, dental materials, lithography, photoresist, etc.
TCI Organic-Inorganic Perovskite Precursors
"Perovskite" originates from the mineral name of calcium titanate (CaTiO3) and the compounds with formula of ABX3 generally belong to a perovskite-type compound, where the A is a divalent and B is a tetravalent metal ion. A perovskite with cubic or orthorhombic phases shows ferroelectricity, for instance, barium titanate (BaTiO3) is a ferroelectric or piezoelectric material. High temperature superconductive oxides with a unit of copper oxide are obtained from all perovskite compounds. These perovskite compounds consist of metal ions and oxygen atoms, and are manufactured by a physical procedure (eg. sintering method) Modification of the metal ion and a changing ratio of the metal ion components can drastically control physical properties of the perovskite. In addition to the oxide perovskites, halide-based perovskites are also well known.
On the other hand, one can replace the cationic component with an organic ammonium at the A site. In this case, a chemical method can provide a perovskite compound. This perovskite compound is called an "organic-inorganic perovskite compound", because it contains an organic component. A metal ion component usually involves tin or lead. This perovskite compound has the general formula [(RNH3)mMXn], in which modifications of metal (M), halide (X) and organic groups (R) precisely control physical properties. Among them, the tin perovskite is relatively better for electrical conduction, and the lead one is better for optical properties. A chemical modification of the halide controls band gap. Selection of organic onium halide, metal halide and their mixing ratio changes the component ratio of the halide. The organic groups are selected from methyl, long alkyls, phenyl, benzyl, phenethyl and so on. Diversity of these organic groups allows controlling the structure of a perovskite compound. For instance, a perovskite compound with R = methyl provides [(MeNH3)MX3] having a three-dimensional cubic perovskite structure. A perovskite compound with R = CnH2n+1 (n ≥ 2) provides a twodimensional perovskite layer and the length of alkyl group can control the inter-layer distance.
TCI Organic Transistor (OFET) Materials
 Materials SNIP.PNG)
Organic field-effect transistors (OFETs) are promising components for the next-generation electronic devices. In 1984, OFET research began with the first report of mobility in a merocyanine dye-based field-effect device by Kudo et al. Since high hole mobility (1.5 cm2 /Vs), which comparable to that of amorphous silicon, was achieved using a pentacene-based OFET device in 1997, the possibility of a practical application of OFET’s became realistic and the research field became quite popular worldwide. While silicon has performed well in devices, the inorganic nature of them prohibits flexible structures. As a result, OFETs have attracted much attention for their potential to be flexible, thin and light-weight, which could be applicable for foldable electronic circuits and implantable biometric sensors.
A noted potential application with OFET’s involves their “printability”. Printed electronics are an innovative technology for mass and low cost device productions, which could allow for the production of high density and large circuits on flexible substrates such as paper and plastic films. A fusion of “Printed electronics” and “Organic transistors” could offer especially promising technology by allowing for low cost and large scale manufacture of various functional devices.
One of the functional parameters evaluated in organic semiconductor materials is mobility (μ), which indicates how fast the holes (p-type) or electrons (n-type) within the semiconducting layer move. A material that possesses high carrier mobility is required for producing high-speed circuits. OFET devices are a largely simple construction containing an organic semiconductor layer, an insulating layer, and source-drain-gate electrodes. These components allow for the evaluation of fundamental transistor parameters including mobility, operation voltage, and driving stability.
TCI Organic Light-Emitting Diode (OLED) Materials
 Materials SNIP.PNG)
Organic light-emitting diode (OLED) devices have received much attention, because they are expected to be a next generation display and light source, thanks to lightweight and flexible organic materials. The OLED was focused on practical use, after Tang et al first observed the OLED device by use of a two layered organic thin film. Adachi et al further reported a three layered device, in which a host layer is sandwiched by hole transport and electron transport layers. In addition, they reported a two layered system, in which one layer has roles of host and electron transport properties. A five layered system including electron injection and hole injection layers has been also studied in order to improve the efficiency of carrier injection. One can control RGB colors of emission by selection of a dopant into a host layer. A suitable combination of the dopant can give a white colored device. An application using the white organic light-emitting device (WOLED) is an OLED light panel.
An amorphous material is useful for an OLED device, because it is transparent, homogeneous, isotropic and easily processible. A practical OLED device further requires excellent heat-resistance and durability. Many hole transport materials based on triphenylamine derivatives (TPD) are widely usable, because they are heat-resistant and amorphous. In addition to the TPDs, oxadiazole derivatives (PBD) having an electron transport property,9) Alq3 as a host material, and blue emissive distylyl derivatives are fundamental materials for amorphous OLED devices.
TCI Mitsunobu Reaction
In 1967 Mitsunobu reported the reaction of alcohols and carboxylic acids in the presence of diethyl azodicarboxylate (DEAD) and triphenylphosphine (TPP) to give the corresponding esters in high yield.1) This reaction involves the activation of an alcoholic hydroxyl group and the subsequent carbon-oxygen bond cleavage caused by an attacking carboxylate anion, to give an ester with complete Waldeninversion of the alcohol stereocenter. Furthermore, carboxylic acids are not the only nucleophiles which can be used in this reaction. Imides and thiols can also be used as the nucleophilic component. This reaction constitutes one of the most important organic reactions, and it is therefore called the "Mitsunobu reaction" after its developer.
The Mitsunobu reaction has found widespread use in many fields because of its high reliability and extensive versatility. For example, searching SciFinder® for the keyword "Mitsunobu," from 1967 to today, one encounters about 4,500 related reports, indicating the high utility of this reaction. However, the generation of phosphine oxide and hydrazinedicarboxylate as by-products often makes the isolation of pure product difficult. Furthermore, the pKa of the usable acidic component must be below 13, but preferably below 11. Since the Mitsunobu reaction has its versatility, efforts have been made toward widening the utilization scope.
TCI Ionic Liquids
As seen above, ionic liquids are salts, consisting of cations such as imidazolium, pyridinium, quaternary ammonium and quaternary phosphonium, and anions such as halogen, triflate, tetrafluoroborate and hexafluorophosphate, which exist in the liquid state at relatively low temperatures. Their characteristic features include almost no vapor pressure, non-flammability, non-combustibility, high thermal stability, relatively low viscosity, wide temperature ranges for being liquids, and high ionic conductivity. When an ionic liquid is used as a reaction solvent, the solute is solvated by ions only, where the reaction proceeds under quite different conditions as compared to using water or ordinary organic solvents. Hence, they are expected to exhibit unconventional reactivity, and their applications in a variety of organic reactions are being explored.
Ionic liquids containing chloroaluminate as the anion have been investigated for many years. These ionic liquids are not only used as reaction solvents, but also exhibit Lewis acid or Lewis base properties, when the ratio of cations and anions is changed. However, they can only be used under an inert atmosphere or vacuum, due to their high moisture sensitivity. On the other hand, it has been found that ionic liquids containing anions such as hexafluorophosphate form stable salts in air, which lead to the synthesis of numerous stable ionic liquids today. Furthermore, some ionic liquids have very low solubility in water and polar organic solvents. Utilization of this property enables recovery and reuse of ionic liquids, after extracting the product with an organic solvent. That can help to reduce the waste of traditional solvents which are rarely reused. Moreover, ionic liquids have attracted much attention as safe solvents, due to their low volatility.
TCI Building Blocks for Organic Semiconductor
Light and flexible organic semiconductor materials are promising for foldable electronic circuits1) and implantable biometric sensors,2) although such electronic devices are hardly obtained from silicon-based semiconductors. We have developed a printed electronics system giving large scale and highly precise devices on flexible substrates (eg. paper and film) by a printing method thanks to the solubility of organic materials. The printing method is one efficient technology for mass production and low cost production of semiconducting devices.3) Organic photovoltaics (OPV) is a photoelectric conversion device using organic semiconductors. Organic light-emitting diode (OLED) devices have received much attention, because they are expected to be a next generation display and light source, thanks to lightweight and flexible organic semiconductor materials. Organic semiconductor materials are mainly classified into small molecular and polymer types, and an oligomer type is a middle class between them.
TCI Fluorinating Agents, Building Blocks, Fluorinated Bioactive Compounds
The introduction of fluorine into bioactive molecules often results in significant changes in their chemical, physical, and biological properties. Fluorine uniquely affects the property of organic molecules due to the fluorine atom’s blocking effect in metabolic transformations and mimicking of enzyme substrates, and then increases the molecular lipophilicity to enhance bioavailability. Approximately 30% of all agrochemicals and 20% of all pharmaceuticals contain fluorine.1) HMG-CoA reductase inhibitor fluorostatin (atorvastatin), antibiotic fluoroquinolone (levofloxacin), and antitumor fluoronucleoside (tegafur) are successful examples of the introduction of fluorine into organic molecules (Fig. 1). Therefore, fluorinating agents are useful tools for the synthesis of pharmaceutical and agricultural compounds.
Since there are few naturally occurring fluorine containing compounds, it is necessary to fluorinate organic compounds at a certain stage of the syntheses. Though fluorine gas and hydrogen fluoride are used as fluorine sources, they are very toxic and corrosive and require special equipment and techniques for handling them. Therefore, alternate fluorinating agents have been developed, which are used in laboratories to easily introduce a fluorine atom at selected positions of the compounds. The fluorinating agents are roughly classified into two categories: nucleophilic and electrophilic. Nucleophilic fluorinating agents are those where the fluoride anion serves as a reaction active species. Electrophilic fluorinating agents are those where the electron-deficient fluorine atom serves as a reaction active species. In addition, a fluorinated building block is used as a fluorine source, which has both a fluorine atom and a replaceable functional group in a molecule.
TCI Cosmetic Materials
In the never ending search to improve and retain their youthful appearance, more and more people are turning to cosmetic applications for their skin. In an effort to keep their skin healthy, as well as cover up blemishes and wrinkles, more people are seeking cosmetic products which contain moisturizers, whitening agents, and sunscreens. Below are listed some high quality products available from us for use in cosmetics.
TCI Chemical Compounds Purified by Sublimation
Reagent purity is paramount in countless applications, and is of particular importance when involving electronic materials including polyaromatic hydrocarbons. Pentacene (P0030, P2524) and N,N’-diphenyl-N,N’-di(m-tolyl)-benzidine (D3236) in particular have garnered increased interest for their applications in organic semiconducting materials. The purification of organic compounds is almost entirely conducted via column chromatography or recrystallization. These mainstay procedures are highly effective, but are limited to compounds soluble in organic solvents.
Many electronic materials including PAHs due to their extensive π conjugation and aromaticity are poorly or completely insoluble in organic solvents. Fortunately, this very π conjugation lends to both high volatility with a relatively high sublimation temperature lending to sublimation purification being a highly effective purification avenue. To address research and industry demands, TCI has introduced several electronic materials purified by sublimation which can be readily and reliably used in a variety of research applications.
TCI C-H Bond Activation Reaction
Recently, there have been a large number of reports on “C-H bond activation reaction”. C-H bond activation is a methodology for directly forming carbon-carbon bonds by activating a carbonhydrogen bond, which is the most fundamental linkage in organic chemistry. Traditional cross coupling reactions have been one of the most useful synthetic methods for the formation of carboncarbon bonds. However, the cross coupling reaction requires extra procedures for preparing organic halides (or triflates) compounds, and organic boron or metal compounds. On the other hand, the C-H bond activation can reduce these procedures, thus making this reaction a cost-effective and ecofriendly system.
