摘要
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-coEDOT) 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 copolymer film shows high optical contrasts and satisfactory response times.
