solution. Concomitantly with micellization, strong changes in the photochemical behaviour occur. In particular, monophotonic photoionization is only observed above the critical micelle concentration (CMC.). Cooperative effects associated with self-assembly of this amphiphilic redox chromophore leading to local electrostatic barriers are evoked to explain these effects.
合成了吩噻嗪的表面活性剂衍生物,其能够在水溶液中形成胶束。与胶束化同时,发生光化学行为的强烈变化。特别是,仅在临界胶束浓度(CMC。)以上才能观察到单光子光电离。引起与这种两亲性氧化还原生色团的自组装相关联的协同作用导致局部静电屏障,被认为是解释这些作用的原因。
