摘要

钌(II)三(联吡啶基)染料分子(Ru(II)(bipy)/spl middot/2Cl/ sub2 /)作为增感剂，在360 ~ 500 nm范围内吸收可见光。光激发敏化剂可以将载流子转移到电子受体(苯基紫素)上并引起氧化还原反应。随着这些氧化还原反应，溶液的颜色发生变化，而LiI或三乙胺(TEA)作为电子延迟剂加入到溶液中。染色和漂白过程的测试细胞充满了溶液被检查暴露在不同的光强度。

Dye molecule/viologen system for a novel photoelectrochromism

Ruthenium (II) tri-(bipyridyl) dye molecules (Ru(II)(bipy)/spl middot/2Cl/sub 2/) were used as a sensitiser which absorbs the visible light in the region of 360-500 nm. The photoexcited sensitiser can transfer charge carriers to an electron acceptor (benzyl-viologen) and lead to redox reactions. Along with these redox reactions the solution changes its color, while LiI or triethylamine (TEA) are added in the solution as electron delays. The coloring and bleaching processes of a test cell filled with the solution were examined exposing to different light intensities.
