| 摘 要： | 设计合成了一种新型的基于咔唑单元的树枝状3, 6-双噻吩咔唑衍生物(BTCPh),通过电化学聚合法制备出其均聚物及与3, 4-乙烯二氧噻吩(EDOT)的共聚物薄膜.利用电化学工作站-紫外可见光谱联用装置对两种聚合物的光谱电化学和电致变色(EC)性能进行表征.测试结果表明,均聚物(PBTCPh)薄膜在不同电压下可显示黄、绿、蓝、灰四种颜色;而EDOT单元的引入使共聚物P(BTCPh-EDOT)进一步增加了掺杂态,从而显示出更加丰富的五种颜色(橙、绿、棕绿、蓝、灰).此外,两种聚合物薄膜均具有良好的光学对比度和快速的响应速度,因而使其在智能窗及显示器方面展现了潜在的应用前景.

| Abstract: | A novel dendritic carbazole derivative (BTCPh) was designed and synthesized by simple chemical route. Its homopolymer and copolymer of BTCPh with (3, 4-ethoxylene dioxythiophene) (EDOT) were electrochemically synthesized and characterized. Cyclic voltammetry and UV-Vis spectroscopy were used to investigate the spectroelectrochemical and electrochromic properties of the two polymers. The copolymer P(BTCPh-EDOT) film revealed richer electrochromic color than that of the homopolymer PBTCPh film (yellow, green, blue, and grey) and showed five different colors (orange, green, brown-green, blue, and grey) under various potentials, which may be attributed to the introduction of the EDOT unit generating more doped states of the polymer, resulting in richer colors. Electrochromic switching tests indicated that both polymers possess good optical contrast and fast switching times. These properties show promise for potential applications on smart windows and displays. |
