Indium Tin Oxide (ITO) electrodes. The presence of the dansyl group in the monomer precursor prevents the electropolymerization in usual systems, such as (C4H9)4NBF4 in acetonitrile (CH3CN). For this reason, it was added 20% boron trifluoride diethyl etherate (BFEE) to this system, to achieve electropolymerization. The resulting poly[3-(N-pyrrolyl)propyl dansylglycinate] (PPyPDG) films displayed electrochromic
通过简单的合成路线制备带有丹磺酰基取代基的荧光吡咯衍生物,并将其电聚合到氧化铟锡(ITO)电极上。单体前体中丹磺酰基的存在会阻止常规体系中的电聚合,例如乙腈(CH 3 CN)中的(C 4 H 9)4 NBF 4。因此,向该体系中添加20%的三氟化硼二乙醚(BFEE),以实现电聚合。所得的聚[3-(N-吡咯基]丙基丹酰甘氨酸盐](PPyPDG)膜显示出电致变色行为。它们的颜色从中性状态的黄绿色到氧化态的灰绿色不等。此外,PPyPDG是一种良好的绿色发光材料。因此,PPyPDG膜可能会潜在地应用于显示器和光电设备。
