Abstract

A series of porphyrin derivatives containing carboxylic-, sulfo-, and phenyl groups, 5,10,15,20-tetrakis(4-carboxyphenyl)-porphyrin(H₂TCPP), 5,10,15,20-tetrakis(4-sulfophenyl)-porphyrin(H₂TSPP), and 5,10,15,20-tetraphenyl)-porphyrin(H₂TPP), were used as sensitizers for porous nanocrystalline TiO₂. The photosensitization and the absorption properties dye absorbed TiO₂ electrodes were examined. The incident photo to current efficiencies (IPCE) of 40% for H₂TCPP/TiO₂ has been obtained at the wavelength of a maximum absorption of the dye in the presence of iodide as an electron donor. Under the same conditions, the electrode of H₂TSPP and H₂TPP shown the efficiencies of 10% and 2%, respectively. We also explored the influence of different substitute on absorption spectra of TiO₂ electrode coated with these dyes.
