BODIPY–vinyl dibromides as triplet sensitisers for photodynamic therapy and triplet–triplet annihilation upconversion

Abstract

We devised a new generation of halogen-based triplet sensitisers comprising geminal dibromides at the vinyl backbone of a BODIPY fluorophore. Incorporating geminal dibromides into the π-conjugation of BODIPY enhanced intersystem crossing due to the heavy atom effect, which in turn improved the extent of excited triplet states.
