Helical Spin Polymer with Magneto-Electro-Optical Activity

A chiral π-conjugated polymer bearing a stable radical side group was synthesized by electrochemical polymerization in a cholesteric liquid crystal. The polymer thus obtained shows paramagnetism as well as electro-and optical activity. The polymer exhibit

Destabilizing Character of a π-Conjugated Boron Center in Bisphenol Radicals

Although boron-containing radicals are promising materials for molecular electronic devices, the electronic effect of the σ-donating yet π-accepting boron center on the stability of open-shell species has been less discussed. In this work, the role of a tricoordinate boron center in π-conjugated radicals was explored through electron paramagnetic resonance measurement of several boron-linked bisphenol radicals and diradicals. Replacing the bridging methine fragment of a neutral Galvinoxyl radical with an arylboryl group led to the corresponding boron-linked radical anion that requires excessive steric protection at the boron center to be persistent in solution. Experimental and theoretical investigations revealed that the introduction of boron would diminish the quinoidal character of the phenoxyl radical and increase both the electrophilicity and nucleophilicity of the open-shell species. Therefore, it is important to consider the steric protection of the boron center in boron-containing π-conjugated organic radicals.

Photoelectric conversion element

A photoelectric conversion element having high photovoltaic conversion efficiency is provided. The photoelectric conversion element includes a first electrode, a second electrode arranged opposite to the first electrode, and an electron transport layer provided on a face of the first electrode, and the face is opposite to the second electrode.

Novel anti-inflammatory agents, pharmaceutical compositions and methods for reducing inflammation

The present invention relates to novel specifically-substituted phenyl compounds, especially substituted di-tert-butyl phenol derivatives, which are effective as anti-inflammatory, analgesic and/or antipyretic agents. These phenyl compounds are substituted with a low molecular weight alkyl chain which terminates in a specific unsaturated functional group. These unsaturated functionalities are --C CH, C=CH2, C=C=CH2, and aldehydes in the form of their acetals. The present invention further relates to pharmaceutical compositions which contain an anti-inflammatory agent of the present invention and a pharmaceutically-acceptable carrier. Finally, the present invention relates to methods for treating diseases characterized by inflammation, such as rheumatoid arthritis and osteoarthritis, in humans or lower animals. Such methods comprise administering to a human or lower animal in need of such treatment a safe and effective amount of an anti-inflammatory agent or composition of the present invention.

Novel synthesis of 3,3-substituted dihydrobenzisothiazole-1,1-dioxides and -2,3-dihydronaphtho-1,2-thiazine-1,1-dioxides

This invention relates to a method of synthesizing certain 3-(carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxides (and -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) by reacting (a) a 4-OP-carbocyclic aryllithium compound wherein P is a protecting group and (b) a 3-(carbocyclic aryl)benz[d]isothiazole-1,1-dioxide wherein said 3-(carbocyclic aryl) moiety is other than a 3-(4'-OP-carbocyclic aryl) moiety to give (c) the corresponding 3-carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxide. The -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides are prepared in the same manner by reacting a 3-(carbocyclic aryl)naphtho[1,8-de]-1,2-thiazine-1,1-dioxide with said 4'-OP-carbocyclic aryllithium compound. In a further embodiment, the compounds synthesized according to the foregoing method are reacted with a carboxylic acid halide to give the corresponding 2-carbonyl-substituted 2,3-dihydrobenz[d]isothiazole-1,1-dioxide (or -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) followed by removing the protecting group, P, with weak acid to yield certain phenol and 1-naphthol sulfam(na)phthaleins useful, e.g., as optical filter agents and filter agent precursors in photography.
