Strong donor-acceptor couplings in a special pair-antenna model

Strong donor-acceptor couplings in a special pair-antenna model

A special pair model composed of two cofacial zinc porphyrins (acceptor) linked to a free base (donor) acts as an energy transfer dyad. Despite the absence of conjugation, ππ*/charge transfer excited states and ultrafast energy transfer (∼5 ps) are noted.
