A series of monomers of 5,15-dithienyl porphyrin, 5,15-di-bithienyl porpyrin and their metal complexes were synthesized in high yields. 5,15-Di-bithienyl porphyrin and its metal complexes were polymerized by chemical...A series of monomers of 5,15-dithienyl porphyrin, 5,15-di-bithienyl porpyrin and their metal complexes were synthesized in high yields. 5,15-Di-bithienyl porphyrin and its metal complexes were polymerized by chemical oxidation using FeCl3 as oxidant (>90%) for making organic conductor and the linear porphyrin-thiophene co- polymers were obtained. The structures of the copolymers were identified by elemental analysis and IR spectra. The conductivity of poly 5,15-di-bithienyl porphyrin was measured to reach over 10-6 S/cm. 5,15-Dithienyl porphyrins and its metal complexes could not be polymerized under the similar conditions, but could be polymerized by elec- trochemical oxidation on the gold-plate electrode.展开更多
