electron-transfer process within the triads. These processes can be elicited either in the excited state of the perylenetetracarboxylic diimide chromophore or in the excited state of the porphyrin chromophore. The existence of photoinduced charge-separated states within triads in solution was confirmed by steady-state photolysis in the presence of methyl viologen (MV2+) as a sacrificed electron acceptor and
合成了在可见光谱区域具有扩展吸收的光活性富勒吡咯烷-苝四羧酸二亚胺-卟啉三元组 (FPP) 及其锌类似物 (ZnFPP)。稳定的吸收光谱和循环伏安法 (CV) 测量显示三元组内基态的成分发色团之间的电子相互作用相当弱。初步的荧光测量表明在三联体中发生了光致电子转移过程。这些过程可以在苝四羧酸二亚胺生色团的激发态或卟啉生色团的激发态中引发。在甲基紫精 (MV2+) 作为牺牲电子受体和 1-benzyl-1,4-dihydronicotinamide (BNAH) 作为牺牲电子的存在下,通过稳态光解证实了溶液中三联体中光诱导电荷分离态的存在捐赠者。光伏器件是在三合会的基础上制造的,并具有...
