Five novel near-infrared BODIPY dyes were prepared for improved singlet oxygen generation using thiophene and bromine. Theoretical, optical, photostable, and singlet oxygen generation characteristics of these dyes were assessed. Predicted excitation energies by TDDFT calculations were in good agreement (Delta E approximate to 0.06 eV) with experimental data. All five dyes showed both excitation and emission In the NIR range. In particular, two dyes having sulfur and bromine atoms showed efficient singlet oxygen generation with high photostability.

A series of thiophene-fused boron dipyrromethene (BODIPY) photoredox catalysts are systematically examined to identify structure–reactivity relationships that enable efficient near-infrared light-induced polymerizations.
