Towards improved halogenated BODIPY photosensitizers: clues on structural designs and heavy atom substitution patterns

The singlet oxygen ( O ) production quantum yield (Φ ) of 14 halogenated BODIPY dyes has been determined (0.01 < Φ < 0.99). O production and photostability have been evaluated considering the BODIPY structure, the substitution pattern, and the number and type of heavy atoms and quenching rate...

Summary:The singlet oxygen ( O ) production quantum yield (Φ ) of 14 halogenated BODIPY dyes has been determined (0.01 < Φ < 0.99). O production and photostability have been evaluated considering the BODIPY structure, the substitution pattern, and the number and type of heavy atoms and quenching rate constants of O by the sensitizer. In view of the experimental results and principal component analysis (PCA), guidelines for an improved design of efficient and photostable halo-BODIPY sensitizers are proposed.
