N2 - We have fabricated and compared photocurrent generation properties of electropolymerized films consisting of 2,2'-bithiophene and a porphyrin derivative, 5,10,15,20-tetra(3-thienyl)-21H,23H-porphyrin or 5,10,15,20-tetra(2-thienyl)-21H,23H-porphyrin. It was found that the location and the concentration of porphyrin moieties in the films were different between the two porphyrin monomers, and the polymer film with the former porphyrin gave larger photocurrent than the latter. The result indicates that the molecular design of the polymer electrode is very important for effective photocurrent generation.
