在三氟化硼乙醚和乙腈的二元溶剂体系中，通过3-甲基噻吩（3 MeT）和苯并蒽酮的单体混合物的电化学氧化，成功制备了一种新型共聚物聚（3-甲基噻吩-co-苯并蒽酮）。通过一系列不同单体投料比的实验，研究了单体投料比对电化学共聚反应及共聚物膜综合性能的影响。所得共聚物兼有聚苯并蒽酮和聚（3-甲基噻吩）的优点，如荧光性能好、氧化还原活性好、热稳定性高、导电性好等。采用紫外-可见光谱、红外光谱和热分析对共聚物的结构和热稳定性进行了表征和研究。荧光光谱研究表明，该共聚物在普通有机溶剂中具有良好的绿色或黄-绿色发光性能，掺杂态在499 nm处有较强的荧光发射，去掺杂态在529 nm处有较强的荧光发射。
Poly(3-methylthiophene-co-benzanthrone), a novel copolymer, was successfully achieved by electrochemical oxidation of the monomer mixtures of 3-methylthiophene (3MeT) and benzanthrone in the binary solvent system containing boron trifluoride diethyl etherate and acetonitrile. A series of experiments with different monomer feed ratios were carried out to investigate the influence of monomer feed ratio on the electrochemical copolymerization and the overall properties of the copolymer films. The resulting copolymer possesses the advantages of both polybenzanthrone and poly(3-methylthiophene), such as considerable fluorescence property, good redox activity, high thermal stability, and relatively high electrical conductivity. Ultraviolet–visible, FT-IR, and thermal analysis were used to characterize and investigate the structure and thermal stability of the copolymers. Fluorescence spectroscopic studies revealed that the copolymer dissolved in common organic solvents was a good green or yellow-green light emitter, with a strong emission at 499ánm in doped state and 529ánm in dedoped state.
