Abstract

Electron-transfer reactions in Fréchet-type dendrimers with biphenyl peripheral groups and a ruthenium core were investigated by pulse radiolysis techniques. Fast electron-transfer rates found in the two ruthenium dendrimers suggest a very efficient electronic coupling between the peripheral donor groups and the core acceptor.

摘要

通过脉冲辐解技术研究了具有联苯外围基团和钌核心的Fréchet型树枝状大分子中的电子转移反应。在两种钌树枝状大分子中发现的快速电子转移速率表明，外围供体基团与核心受体之间存在非常有效的电子耦合。
