(Asc-) in the inner waterpool to methylviologen (MV2+) in the outer aqueous solution was driven by the irradiation of pyrene derivatives embedded in the vesicle bilayers. The initial rate of MV2+ reduction is dependent on the substituent group of the pyrenyl ring; a hydrophilic functional group linked with the pyrenyl ring by a short methylene chain acts as a sensitizer for the electron transport.

通过嵌入在囊泡双层中的pyr衍生物的驱动,从囊泡双层中的内能电子传输从内部水池中的抗坏血酸盐(Asc-)到外部水溶液中的甲基紫精(MV2 +)。MV2 +还原的初始速率取决于the环的取代基。通过亚甲基短链与the环相连的亲水性官能团充当电子传输的敏化剂。使用(1-吡啶基)链烷酸(1a-c)作为敏化剂的机理研究表明,电子传输主要是由Asc-对the的单重激发态进行还原性猝灭而引发的,并通过涉及电子之间交换的机理进行located位于囊泡双层的内部和外部界面。
