Electrochemical properties of this new hemicyanine dye were studied by means of cyclic voltammetry and in situ spectrochemistry. The result shows that the hemicyanine dye has electrochemical characteristics. In this paper, we report the determination of the reductive peaks.展开更多
A series of amphiphilic azo-methine dyes with different relative positions of electron-accepting groups, (E)-N-octadecyl-2-[2-(4-N,N-dimethylaminophenyl)azomethinyl]quinolinium iodide(QN2), (E)-N-octadecyl-4-[2-(4-...A series of amphiphilic azo-methine dyes with different relative positions of electron-accepting groups, (E)-N-octadecyl-2-[2-(4-N,N-dimethylaminophenyl)azomethinyl]quinolinium iodide(QN2), (E)-N-octadecyl-4-[2-(4-N,N-dimethylaminophenyl)azomethinyl]quinolinium iodide(QN4) and (E)-N-octadecyl-6-[2-(4-N,N-dimethylaminophenyl)azomethinyl] quinolinium iodide(QN6) were synthesized. These dye molecules were successfully transferred onto quartz by Langmiur-Blodgett(LB) technique. We studied the second-harmonic generation(SHG) of their monolayers and found that the effect of relative position of acceptor group on SHG can not be negligible.展开更多
