The golden goal of entatic state model design: lowering the internal reorganization energy leads to exponential increase in electron transfer rate

Abstract

We report a novel guanidine quinolinyl entatic state model system with an electron transfer rate on the order of 10⁵ M⁻¹ s⁻¹ and remarkably little internal reorganization. Comparison between this system and previously reported TMGqu systems reveals an exponential correlation between the internal reorganization energy and the electron transfer rate.
