摘要

Electron transfer (ET) is one of the most fundamental processes in nature,biological systems,and optoelectronic devices.The in-depth ET investigations of synthetic materials are of great significance for the understanding of those occurring in natural systems.Mixed-valence (MV) compounds,consisting of two bridged redox motifs that are structurally identical but different in valence,provide an appealing platform for this purpose [1].To date,a vast number of MV compounds have been synthesized and examined.However,successful or even partially successful examples of MV compounds with efficient electronic coupling and ET through a hydrogen bond are very limited [2,3].The difficulty in building hydrogen bond-bridged MV compounds is mainly caused by the dynamic nature and elusive chargetransporting property of hydrogen bond and its decreased stability upon redox reactions.
