摘要

合成了三种基于3取代聚噻吩的共聚物。聚（3-己基噻吩-co-3-甲氧基噻吩）P（3HT-co-3MOT）共聚物的3HT和3MOT单元的比例分别为2:1、2:1和1:2，采用红外光谱（FT-IR）、紫外可见性（UV-Vis）、热分析（TG）、循环伏安法和时间吸收法对其进行表征。表征证实了材料的成功形成，以及从橙色到蓝色的可逆颜色变化（电致变色）。光学和光谱电化学研究表明，调整聚合物链中单体单元之间的比例是一种可行的策略，可以微调材料的最大吸收波长和电致变色响应时间。

Copolymers derived from 3-hexylthiophene and 3-methoxythiophene as potential active layers for polymeric electrochromic devices

Three copolymers based on 3-substituted polythiophenes were synthesized. All copolymers, poly(3-hexylthiophene-co-3-methoxythiophene) P(3HT-co-3MOT), with different ratios between the 3HT and 3MOT units (2:1, 2:1, and 1:2), were characterized by FT-IR, UV-Vis, thermal analysis (TG), cyclic voltammetry, and chronoabsorptometry. The characterizations confirmed the successful formation of the materials, as well as a reversible color change from orange to blue (electrochromism). The optical and spectroelectrochemical studies showed that adjusting the ratio between the monomer units in the polymer chain can be a viable strategy for fine-tuning both the maximum absorption wavelength of the materials and their electrochromic response time.

期刊介绍： This journal is an international medium for the rapid publication of original research papers, short communications and subject reviews dealing with research on and applications of electronic polymers and electronic molecular materials including novel carbon architectures. These functional materials have the properties of metals, semiconductors or magnets and are distinguishable from elemental and alloy/binary metals, semiconductors and magnets.
