Novel applications of 2-cyanoethylanilines in the synthesis of conjugated primary and secondary anilines

2-Cyanoethyl anilines were controllably cleaved by 1equiv of potassium t-butoxide in dry THF with a reaction that can be used in situ with the Wittig reaction to synthesize conjugated primary and secondary anilines.

Photoelectric conversion properties of four novel carboxylated hemicyanine dyes on TiO2 electrode

Four hemicyanine derivatives, 2-[4-(N-ethyl-N-carboxyethyl)amino]phenylethenyl-1,3,3-trimethyl-3H-indolium iodide (BIDC1), 2-[4-(N,N-dicarboxyethyl)amino]phenylethenyl-1,3,3-trimethyl-3H-indolium iodide (BIDC2), 2-[4-(N-ethyl-N-carboxyethyl)amino]phenylethenyl-1,1,3- trimethyl-1H-benz[e]indolium iodide (BIDC3) and 2-[4-(N,N-dicarboxyethyl) amino]phenylethenyl-1,1,3-trimethyl-1H-benz[e]indolium iodide (BIDC4), have been synthesized and identified with regard to their structures and electrochemical properties. It is found that the absorption spectra of BIDC3 and BIDC4 are broader than that of BIDC1 and BIDC2 because the former two have one more benzene ring on the electron acceptor side. Upon adsorption on a TiO2 electrode, the absorption spectra of the four BIDC dyes are all broadened forward to both red and blue sides compared with their respective spectra in ethanol solution. BIDC2 (or BIDC4) bearing two carboxyl groups, has about two (or three) times more adsorption and a broader absorption spectrum on TiO2 film compared with BIDC1 (or BIDC3) which consequently leads to a better light-to-electricity conversion property. Among the four hemicyanine dyes, BIDC4 generated the highest photoelectric conversion yield of 4.9%, with a short-circuit photocurrent of 21.4 mA cm-2, an open-circuit voltage of 424 mV, and a fill factor of 0.49 under irradiation with 90.0 mW cm-2 white light from a Xe lamp.

OPTICAL DATA CARRIER COMPRISING IN ITS INFORMATION LAYER A HEMICYANINE DYE AS THE LIGHT-ABSORBING COMPOUND

The invention relates to an optical data carrier which comprises a preferably transparent substrate which is optionally already coated with one or more reflective or protective layers, to the surface of which an information layer which can be written with light, optionally one or more reflective layers and optionally a protective layer or an additional substrate or a cover layer are applied. Said data carrier can be written and read with blue light, preferably laser light. The information layer comprises a light-absorbing compound and optionally a binder. The invention is characterized in that a least one hemicyanine dye of formula (I), wherein either R1 represents methyl, R2 represents hydrogen, chlorine, methyl or methoxy, R3 represents methyl, ethyl, propyl, butyl, chloroethane or cyanoethane, R4 represents chloroethane or cyanoethane and An-represents hexafluorophosphate, or R1 represents methyl, R2 represents hydrogen, chlorine, methyl or methoxy, R3 represents ethyl, propyl, butyl, chloroethane or cyanoethane, R4 represents chloroethane or cyanoethane and An- represents trifluoromethane sulfonate, (CF3SO2)2N- or perchlorate, is used as the light-absorbing compound.
