摘　　要：以3,4-二溴噻吩作为单体,以三氟化硼乙醚溶液(BFEE)为电解质溶液,通过电化学聚合得到聚(3,4-二溴噻吩)[Poly(3,4-dibromothiophene),PDBrTh],其能够显示亮红色和蓝色之间的可逆变化,并研究了PDBrTh薄膜的电致变色性能,其最快响应时间可以达到1.21 s,循环寿命达到1 800圈.以此薄膜作为电致变色层,制成的全固态PDBrTh基电致变色器件能够实现红色/蓝色的可逆变化,对于丰富电致变色器件的颜色具有重要意义.Poly （3,4-dibromothiophene） （PDBrTh） film was prepared via electropolymerization of 3, 4-dibromo-thiophene in boron trifluoride diethyl etherate. The resulted PDBrTh film can change between vivid red and blue reversiblly. The electrochromic behaviors of PDBrTh film was investigated and the fastest response time is 1.21 seconds, it can be used for 1 800 times. It was used to make an electrochromic devices （ITO ｜｜ PDBrTh ｜｜ Gel electrolyte ｜｜ ITO）, whose color could change between red and blue reversibly, and which was important to compound multi-color electrochromic devices.
