Abstract

A series of phenothiazine-styrylborondipyrromethene compact electron donor/acceptor dyads were prepared to access heavy-atom-free triplet photosensitizers showing red-absorption and especially long-lived triplet states (303 μs), based on the spin orbital charge transfer intersystem crossing (SOCT ISC) mechanism.
