The copolymerization of dibenzofuran(DBF)and 3-methylthiophene(MET)was successfully achieved electrochemically by direct anodic oxidation of the monomer mixtures in boron trifluoride diethyl etherate.The effects of applied polymerization potential and the monomer concentration ratios on the copolymerization were investigated by linear sweep voltammetry and cyclic voltammetry(CV).The structure of copolymer films were investigated by UV-Vis,infrared spectroscopy,thermal analysis.As-formed novel copolymers own...
Poly（benzanthrone-co-thiophene）, a new conducting copolymer, was successfully prepared by direct anodic oxidation of benzanthrone and thiophene （Th） in a binary solvent system containing boron trifluoride diethyl etherate （BFEE） and acetonitrile （ACN）. The as-formed copolymer film electrodeposited with monomer feed ratio of benzanthrone/Th = 1：1 at the applied potential of 1.3 V versus Ag/AgCl exhibited the advantages of both polybenzanthrone and polythiophene, such as active electrochemical behavior, excellent thermal stability, relatively high electrical conductivity and mechanical properties. UV-Vis spectroscopy, 1H-NMR and SEM were used to characterize and investigate the structures and morphologies of the copolymers. Fluorescence spectroscopy studies revealed that the obtained copolymer films show strong emission at about 525 nm. Moreover, the emitting properties of the copolymers could be tuned by changing some parameters during the electropolymerization process, such as monomer feed ratio.
