with better electroactivity and stability and higher electrical conductivity. On the other hand, PEOTT films from all the sovent-electrolytes also showed the electrochromic nature by color changing from gray blue to green, and further kinetic studies revealed that PEOTT had decent contrast ratios (36%), higher coloration efficiencies (212 cm2/C in BmimPF6), low switching voltages, moderate response time
合成了3,4-乙撑二氧噻吩(EDOT)的不对称硫类似物噻吩并[3,4- b ] -1,4-氧杂蒽(EOTT),并通过使用不同的溶剂-电解质体系对它的电聚合进行了比较研究。温度离子液体六氟磷酸1-丁基-3-甲基咪唑鎓盐(BmimPF 6),CH 2 Cl 2 -Bu 4 NPF 6和CH 2 Cl 2 -BmimPF 6)。此外,溶剂和支持电解质对所得聚(thieno [3,4- b]的结构,形态,电化学,电子和光学性质以及电致变色性能的影响对] -1,4-oxathiane)(PEOTT)膜进行了细致的研究。带隙(E g)约为1.6 eV的PEOTT膜可以很容易地在所有溶剂电解质中进行电沉积,并显示出优异的电活性,在宽电位窗中出色的氧化还原稳定性和改善的热稳定性。循环伏安法显示,EOTT可以以较低的氧化电位在电聚合BmimPF 6(〜1.0 V相对于银/氯化银)由于RTIL BmimPF的几个advantanges
