Abstract
Photochemical energy conversion using porphyrins and phthalocyanines was conducted as an example of biomimetics for photosynthesis. The photosynthetic system is first briefly explained with attention to importance of porphyrin compounds. An artificial photosynthetic system possesing a photoexcitation center and incorporating oxidation/reduction catalysts and charge mediators was described. Artificial photosynthesis using porphyrins and phthalocyanies was reviewed with particular consideration to photoexcitation centers, photoinduced charge separation, water oxidation catalysts, proton/CO2 reduction catalysts and charge transport by redox molecules in solid matrixes.
