摘要

A series of anthrylene-substituted phenyleneethynylene dyes having amino/cyano group(s) were prepared by repeating Sonogashira coupling between aryl halides and terminal acetylenes. In UV-vis absorption spectra, the 9,10-anthrylene-substituted dyes showed a strong absorption band of which lambda(max) was located from 502 to 521 nm and epsilon was more than 5.2 x 10(4) L mol(-1) cm(-1) indicating a highly expanded pi-system in comparison with 1,5-anthrylene dye (lambda(max) = 431 nm, epsilon = 2.6 x 10(4) L mol(-1) cm(-1)). Lippert-Mataga plots demonstrated that the amino- and cyano-substituted dyes underwent larger charge separation in the excited states. These acetylenic dyes served as sensitizers of dye-sensitized solar cell to achieve 5.0% of photo-to-current energy conversion efficiency.
