Proton-Coupled Electron Shuttling in a Covalently Linked Ruthenium–Copper Heterodinuclear Complex

A heterodinuclear complex based on a RuII–TPA [TPA = tris(2-pyridylmethyl)amine] complex having a peripheral CuII(bpy)2 (bpy = 2,2′-bipyridine) group bonded through an amide linkage displayed reversible intramolecular electron transfer between the Ru and Cu complex units that can be controlled by protonation and deprotonation of the bridging amide moiety.

一种基于钌(II)-TPA（三(2-吡啶甲基)胺，tris(2-pyridylmethyl)amine）的异双核配合物，其外围带有经酰胺键键合的铜(II)(bpy)2（2,2'-联吡啶，2,2′-bipyridine, bpy）基团。该配合物在钌与铜配合物单元间展现出可逆分子内电子转移行为，且该转移过程可通过桥联酰胺基团的质子化与去质子化实现调控。
