Proton-Induced Switching of Electron Transfer Pathways in Dendrimer-Type Telranuciear RuOs_3 Complexes

摘要

Supramolecular complexes as precursors for molecular devices have attracted much attention in recent years. Molecular switching by an external stimulus is one of the fundamental functions of supramolecular complexes. Prolonation can act us an externaltrigger in complexes containing basic sues. Recently, protonalion has been shoun to induce the switching of fluorescence, redox properties, and electron transfer reactions. The chemical principle underlying the switching ot redox potential, for examplethe reversible protonalion of an uncoordinated nitrogen site in 2-(2-pyridyl)benzimidazole Ru complexes, has been developed.
