摘要:

以3,4-乙烯二氧噻吩(EDOT)和吡咯-3-甲酸(P3C)为共聚单体,EDOT和P3C分别按物质的量比1:1,3:1,5:1,10:1配比,通过电化学聚合制得了4种聚(3,4-乙烯二氧噻吩-吡咯-3-甲酸)薄膜,并依次命名为P(EDOT:P3C)-1,P(EDOT:P3C)-3,P(EDOT:P3C)-5和P(EDOT:P3C)-10.光谱电化学测试结果表明,4种共聚物薄膜都具有优良的电致变色性能,同时具有较好的电化学活性和较高的光学对比度.与聚3,4-乙烯二氧噻吩(PEDOT)相比,P(EDOT:P3C)能展示更丰富的颜色变化,如P(EDOT:P3C)-1薄膜随着电压的变化,可呈现从暗红色、浅褐色、灰蓝色到蓝色的变化.此外,基于EDOT和P3C以及钛氧簇[Ti7(OEt)19O5(CoBr)],我们还设计合成了含钛共聚物薄膜P(EDOT:P3C)-1-Ti,该薄膜不仅具有电致变色性能,而且还具有电催化氧化水的活性.

Abstract:

Four new copolymers P(EDOT:P3C)-1, P(EDOT:P3C)-3, P(EDOT:P3C)-5, P(EDOT:P3C)-10 were prepared via electrochemical co-polymerization using different molar ratios(1:1, 3:1, 5:1, 10:1) of 3,4-ethylenedioxythiophene(EDOT) and pyrrole-3-carboxylic acid(P3C). The prepared four copolymers have good electrochromic properties, high electrochemical activity and good transmittance. Compared with poly(3,4-ethylenedioxythiophene)(PEDOT), the prepared copolymers have more abundant color change. P(EDOT:P3C)-1 has mainly four colors under different potentials, namely, dark red, pale brown, grey blue and blue. P(EDOT:P3C)-3 and P(EDOT:P3C)-5 possess the color change of purple, light purple and blue. P(EDOT:P3C)-10 can be dark purple, light purple and blue under different potentials. In addition, we also prepared a copolymer P(EDOT:P3C)-1-Ti based on EDOT, P3C and polyoxotitanate cluster[Ti7(OEt)19O5(CoBr)]. This film not only exhibits typical electrochromic properties but also has the ability of electric-catalytic oxidation of water.

Key words: Ploymer(3,4-ethylenedioxythiophene-co-pyrrole-3-carboxylic acid), Electropolymerization, Electrochromism, Polyoxotitanate cluster
