The effect of substitution on the optical and electrochemical property was systematically investigated, with the assistance of theoretical calculations. Moreover, the thin films of the resulting molecules 3b and 3e complexed with fullerene produced strong photocurrent response upon irradiation of white light. In addition, 3b and 3e exhibit a positive nonlinear optical response resulting from the two-photon
通过 Diels-Alder 反应构建了一系列带有各种取代基 (3) 的三苯并蒎烯衍生物,然后进行 Scholl 氧化,其中 3b 的分子结构通过单晶 X 射线衍射分析确定。在理论计算的帮助下,系统地研究了取代对光学和电化学性质的影响。此外,所得分子 3b 和 3e 与富勒烯络合的薄膜在白光照射下产生强烈的光电流响应。此外,3b 和 3e 表现出由双光子吸收和激发态吸收过程引起的正非线性光学响应。
