Abstract

Abstract Singlet excitation energy transfer, SEET, can be mediated by a bridge, connecting an energy donor and acceptor, via a superexchange mechanism. The mediation efficiency depends on the energy difference between the first excited states of the donor and the bridge, ΔE DB, as well as the donor–acceptor distance, R DA. We have previously constructed a series of donor–bridge–acceptor, D–B–A, systems that allowed us to study ...
