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

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 pi-conjugation of BODIPY enhanced intersystem crossing due to the heavy atom effect, which in turn improved the extent of excited triplet states.

Automated summary

The new generation of halogen-based triplet sensitisers were developed by incorporating geminal dibromides into the pi-conjugation of BODIPY, enhancing intersystem crossing and excited triplet states.
