我们报道了二氰基苯基光催化剂和热激活延迟荧光（TADF）发射体中一个氰基的光取代。该反应是一些广泛使用的有机光催化剂（例如 4CzIPN）的一般降解途径，表明许多反应中的活性光催化剂可能与 4CzIPN 不同。相反，光替代是多种高还原性光催化剂和蓝色 TADF 发射体的简便途径。
We report the photosubstitution of one cyano group in dicyanobenzene-based photocatalysts and thermally activated delayed fluorescence (TADF) emitters. The reaction is a general degradation pathway for some widely used organic photocatalysts such as 4CzIPN and suggests that the active photocatalyst in many reactions is likely different from 4CzIPN. On the contrary, photosubstitution is a facile route to diverse highly reducing photocatalysts and blue TADF emitters.
