Photosensitizers based on bacteriopurpurinimide derivatives and silica nanoparticles: Synthesis and photophysical properties

Abstract

We report the synthesis and optical characterization of photosensitizers related to bacteriopurpurin-N-propoximide and its derivative substituted with aminoethylamide surface attachment group, and their conjugates with silica nanoparticles. The obtained supramolecular complexes are characterized by long-wavelength fluorescence band and the ability to photogeneration of long-lived triplet states with high quantum yield.
