通过耦合反应合成1-(3-甲基噻吩-2-基)芘(MTP)的单体,应用电化学方法合成一种基于1-(3-甲基噻吩-2-基)芘(MTP)和3,4-乙烯二氧噻吩(EDOT)的新型共轭共聚物,并对其进行表征。采用循环伏安法(CV)、紫外-可见光谱(UV-vis)和扫描电镜(SEM)表征合成的共聚物 P(MTP-co-EDOT)。结果表明：与 MTP和 EDOT均聚物相比,P ( MTP-co-EDOT)薄膜电致变色特性明显,在不同的电势下,可以显示出紫色、棕色、草绿色和灰蓝色4种不同的颜色；共聚物薄膜光学对比度高、响应时间短。

1-(3-methylthiophen-2-yl) pyrene ( MTP) monomer was successfully synthesized via coupling reaction firstly. Then, a new conjugated copolymer based on 1-(3-methylthiophen-2-yl) pyrene (MTP) and 3,4-ethylenedioxythiophene (EDOT) was electrochemically synthesized and characterized subsequently. Characterizations of the copolymer P(MTP-co-EDOT) were carried out by cyclic voltammetry ( CV) , UV-vis spectroscopy and scanning electron microscopy ( SEM) . It is found that P( MTP-co-EDOT) film has distinct electrochromic properties compared to the MTP and the EDOT homopolymers, and it exhibits four different colors ( purple, brown, grass green and dusty blue) under various potentials. Moreover, the co-polymer film shows high optical contrasts and satisfactory response times.
