摘要
以3,6-二噻吩基吡咯并[3,4-c]吡咯-1,4-二酮(TH-DPP)为单体,利用电化学合成的方法在不同的电解质溶液中优化了聚3,6-二噻吩基吡咯并[3,4-c]吡咯-1,4-二酮(PTH-DPP)的制备条件,发现在含30%三氟乙酸(TFA)的三氟化硼乙醚(BFEE)体系中更利于PTH-DPP的电化学制备,并在该体系中成功制备了高性能的PTH-DPP薄膜。通过核磁共振谱图对PTH-DPP的聚合物位点及聚合机理进行了研究,发现聚合的位点位于TH-DPP的C3′和C8′位上。PTH-DPP的表面形貌呈致密状态,且分布均匀有颗粒状突起。
The poly(3,6-dithienylpyrrolo[3,4-c]pyrrole-1,4-dione(PTH-DPP)was successfully prepared by electrochemical polymerization of 3,6-dithienylpyrrolo[3,4-c]pyrrole-1,4-dione(TH-DPP)in a boron trifluoride ether(BFEE)system.The electrochemical performance of PTH-DPP films was tested in different electrolyte solutions.The BFEE system containing 30% trifluoroacetic acid was found to be more conducive to the electrochemical preparation of PTH-DPP.The polymer sites and polymerization mechanism of PTH-DPP were studied by NMR spectroscopy,finding that the polymerization reaction occurs on C3′and C8′.The polymer film has a uniform and dense surface with granular protrusions.
