Vibrational and optical properties of Meso-tetrakis(4-phenylsulfonica-acid) porphyrin decorated with graphene oxide.

Abstract

Functionalized graphene oxide have received much attention in a broad range of applications from light harvesting.The interactions between graphene and Meso-tetrakis(4-phenylsulfonica-acid)porphyrin (H4TPPS42-), especially π-π interactions have also been extensively investigated. The composite material formed stable dispersions was characterized by X-ray diffraction, Transmission electronic microscopies, FTIR, Raman. The effect pH and concentration was study by UV-visible absorption.
