Summary:The sensitization of TiO2 with a wide variety of inorganic and organic dyes for light harvesting has been investigated over the last 2 decades for the development of efficient energy harvesting. Porphyrins, as important biomolecules, have been enjoyed with some applications such as catalysts, photosensitizers, non-linear optical materials, liquid crystal, photodynamic therapy of cancer, solar-energy conversion, molecular binding, energy and electron transfers and light harvesting. To apply the photocatalysts to the organic substrates, it is recommended to activate the phtocatalysts under visible light ranges. For this purpose of the utilizing visible light energy, new porphyrin dye molecules are designed and synthesized. The obtained new porphyrin dye materials are linked to photocatalysts and corresponding photocatalytic effects are monitored and investigated.
