Effective Charge Separation in Intermolecular Complexes of an Electron Donor and a Doubly Branched Triad Assembly: A Model System for Environmental Effects Controlling Electron Transfer

Abstract

Back electron transfer of the redox intermediates generated by irradiation of the supramolecular complex 1 is 104 times slower than in the free triad. In 1, in which a dialkoxybenzene derivative is positioned between two bipyridinium arms of the triad, the distance between the redox centers is greater than in the free RuII complex.
