Several different polythiophenes have been synthesized by direct oxidative polymerization of thiophene monomers under different conditions such as temperature, concentration, and time of the reaction. The chemical structure of each polymer has been characterized by FESEM, FTIR, Raman, XRD, UV-Vis, and TG respectively. The studies indicated that the connection of the thiophene ring depends on the reactive conditions, which can induce varying structure distribution of polythiophene. Experimental results suggest that some certain relations do exist between the chemical structure and material conductivity, and α-α polythiophene has a higher conductivity.

Key words: polythiophene, α-&alpha, connection, conductivity, structure
