| 摘 要： | 5,15-Di-bithienyl porphyrin (1) and its Cu(Ⅱ), Zn (Ⅱ) complexes (2 and 3)[1] were polymerized according to Scheme 1 by chemical oxidation using FeCl3 as oxidant 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 (4) doped with FeCl3 was measured to reach over 10-6 S/cm, which was in the range of semiconductor and higher than that of other porphyrin-thiophene copolymers prepared by Shimidzu. The higher conductivity may be due to the better conjugation between the thienyl group and the porphyrin ring. The thienylporphyrins 7 and 8 could not be polymerized under the similar conditions, but could be polymerized by electrochemical oxidation (working electrode: gold-plate electrode; counter electrode: platinum; reference: standard calomel electrode SEC; solvent: 0.1 mol·dm-3 n-Bu4NClO4 in dry MeCN).
