Abstract

Isomeric o, m, p-polyphenylenes were prepared by oxidation-cationic polymeriation of biphenyl with various proportions of the polymerization components biphenyl-AlCl₃-Cu-Cl₂. The insoluble fraction in chlorobenzene was separated. The insoluble polyphenylenes were then doped with anhydrous FeCl₃, AlCl₃, and SnCl₄ in solutions of acetonitrile (ACN), nitrobenzene (N), and acetone (A). X-ray diffraction, Fourier Transform Infrared Spectroscopy (FTIR), and electrical conductivity measurements were carried out to characterize the undoped and doped materials. Some of the o, m, p-polyphenylenes had semiconductive properties after doping depending on the proportion of biphenyl-AlCl₃-CuCl₂ and the doping system (dopant and solvent).
