Towards the Development of Molecular Wires: Electron Localization, Exchange, and Transfer in Alkyne-Bridged Multinuclear Complexes

摘要

Stepwise assembly of preformed molecular modules around a metal center provides an ,mractive means for constructing mul-ticomponent arrays capable of information storage and transport. To ensure fast and quantitative exchange of information within thearray, the bridge must facilitate strong electronic communication between the components. This situation is realized, at ieast for through-bond electron transfer, when the energy level of the bridge slightly exceeds that of the reactants.
