Abstract

Abstract: The redox properties and electronic spectra of different oxidation state of PHBmaterials(ZnTBP, where TBPrepresents the dianion of meso-tetramethyl-tetrabenzoporphyrin or meso-tetraphenyl-tetrabenzoporphyrin or meso-tetra(p-toly)-tetrabenzoporphyrin or meso-tetranaphthyl-tetrabenzoporphyrin)were investigated by electrochemistry and in-situ UV-visible spectroelectrochemistry in CH₂Cl₂, THFand DMSO.The redox potentials of ZnTBPseries and electronic absorption spectra of ZnTBP⁺ and ZnTBP²⁺ were obtained, and the relationship between excited state redox properties and photochemical spectral hole burning was discussed.

Key words: Photochemical spectral hole burning, Zinc tetrabenzoporphyrins, Spectroelectrochemistry
