The attachement of SR (R is alkyl or phenyl) makes BODIPY efficiently generate excited triplet state (T<sub>1</sub>) and singlet oxygen with quantum yield up to 0.82 (compared to 0.10 of parent BODIPY). This affords an efficient method to synthesize heavy atom free photosensitizers. This efficient T<sub>1</sub> formation is because SR presence leads to a new excited state S<sub>1</sub>(n,pi*) with an energy smaller but close to the usual S<sub>1</sub>(pi,pi*) state.
