Two kinds of new electroactive polyamides were synthesized from a novel diphenylamine-fluorene skeleton bis(ether amine) monomer “N,N-bis((4-aminophenoxy)phenyl)-2-amino-9,9-dimethylfluorene” with cycloaliphatic and aromatic dicarboxylic acids, respectively. These polyamides were highly soluble in many organic solvents and could be solution-cast into transparent and flexible films. These films were
由新型的二苯胺-芴骨架双(醚胺)单体“ N,N ”合成了两种新型的电活性聚酰胺-双((4-氨基苯氧基)苯基)-2-氨基-9,9-二甲基芴”分别带有脂环族和芳族二羧酸。这些聚酰胺在许多有机溶剂中高度可溶,可以溶液浇铸成透明且柔软的薄膜。这些薄膜几乎无色,在450 nm处的透光率超过90%,截止波长在385-390 nm范围内。这些聚酰胺显示出可逆的氧化还原,具有从无色(中性状态)到绿色(氧化状态)的强烈颜色变化,并且在410 nm处透射率的电致变色对比度高达86%。特别地,衍生自脂环族酸的聚酰胺在固体状态和溶液状态下显示出强的蓝色荧光发射,量子产率分别高达14.5%和58.9%。此外,
