Excitation-dependent electron exchange energy and electron transfer dynamics in a series of covalently tethered N,N-bis(4′-tert-butylbiphenyl-4-yl)aniline – [C60] fullerene dyads via varying π-conjugated spacers

Abstract

Two different classes of electron transfer dynamics, adiabatic and non-adiabatic, are demonstrated for the first time in the same system by selective photoexcitations to donor and acceptor respectively.
