Chemistry Education Grade 03 College of Chemistry and Bioengineering，YiChun University Mentor: Zhou weiqiangElectrochemical polymerization had been proved to be one of the most useful approaches for conducting polymer synthesis. In neutral organic solvents or in aqueous solution, the oxidation potentials of monomers were so high that the qualities of as-formed polymers were usually very poor. On the other hand, the studies of CPs were mainly concentrated on the simple heterocyclic polymers in the past quarter century, such as polyaniline, polypyrrole, polythiophene, etc.. In recent years, high-quality conducting polymers prepared from fused ring aromatic compounds by electrochemical polymerization had attracted great attention. On the other hand, the research about some theoretical problems in conducting polymers was limited due to the greatly insufficiency of spectrum data obtained presently on the conducting polymers. This dissertation focused on the electrosyntheses and polymerization position study of high-quality conducting polymers from dibenzofuran in BFEE High quality poly (dibenzofuran) (PDBF) films were synthesized electroc
