Benzophenone derivatives having various tetraalkylammonium ion in the 4 position (II, III, IV, and V) were found to be much more efficient sensitizers than benzophenone(I) in photooxidation of Leuco Crystal Violet(LCV) to Crystal Violet(CV+) in acetonitrile in air, which was interpreted in terms of the cationic atmosphere effect facilitating the primary electron transfer process from LCV to BP*3.
在乙腈中将无色结晶紫 (LCV) 光氧化为结晶紫 (CV+) 时,发现在 4 位(II、III、IV 和 V)具有各种四烷基铵离子的二苯甲酮衍生物是比二苯甲酮 (I) 更有效的敏化剂在空气中,这被解释为促进从 LCV 到 BP*3 的初级电子转移过程的阳离子气氛效应。
