A series of monomers of 5,15‐dithienyl porphyrin, 5,15‐di‐bithienyl porphyrin and their metal complexes were synthesized in high yields. 5,15‐Di‐bithienyl porphyrin and its metal complexes were polymerized by chemical oxidation using FeCl 3 as oxidant (>go%) for making organic conductor and the linear porphyrin‐thiophene copolymers 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 electrochemical oxidation on the gold‐plate electrode.
