Abstract

Photoexcitation of an electron donor-acceptor linked dyad containing gold(III) and zinc(II) porphyrins (ZnPQ-AuIIIPQ+) results in electron transfer from the singlet excited state of ZnPQ to the metal center of AuPQ+ to produce the charge-separated state (ZnPQ*+-AuIIPQ) which has a long lifetime (10 mus) in nonpolar solvents such as cyclohexane and toluene.

摘要

对含有金（III）和锌（II）卟啉（ZnPQ-AuIIIPQ+）的电子供体-受体连接二元体进行光激发，会导致电子从ZnPQ的单重激发态转移到AuPQ+的金属中心，从而产生电荷分离态（ZnPQ*+-AuIIPQ），该电荷分离态在环己烷和甲苯等非极性溶剂中具有较长的寿命（10微秒）。
