Photochemical Materials Transformation Using Axial-ligand Coodinated Porphyrinatoantimony Complexes

Abstract

Antimony porphysrin (SbTPP) complexes are able to covalently bind with two axial ligands, thus introducing the functionalized group on the axial-ligand. We have investigated the functionality and material transformation using the functionalized SbTPP complexes. The SbTPP having difluorobornyl-5-dipyrrinylphenyl (Bdpy) group was analyzed under irradiation of Bdpy moiety in term of axial ligand-to-porphyrin energy transfer. The SbTPP having azacrown ether on axial ligand was analyzed from the standpoint of the metal ion-recognition. The silica-gel supported SbTPP was used as visible-light driven photocatalyst for dechlorination from chlorophenols, and photo-epoxidation of cycloalkenes, and bactericidal effect.
