Spin–orbit charge transfer intersystem crossing in perylenemonoimide–phenothiazine compact electron donor–acceptor dyads

Abstract

The spin-orbit charge transfer intersystem crossing (SOCT-ISC) of perylenemonoimide-phenothiazine compact dyads was shown to depend on the molecular geometry and the vector dipole orientations of the two chromophores, and the dyads show high triplet state quantum yields (57%).
