  2,8-二（咔唑-9-基）二苯并噻吩及其S，S-二氧化物衍生物的荧光和电致变色聚合物

  摘要：

  我们报告了两种咔唑封端的单体，即2,8-二（咔唑-9-基）二苯并噻吩（SCz）和2,8-二（咔唑-9-基）二苯并噻吩S，S-二氧化物（通过FeCl 3氧化偶联和电聚合工艺制备SO 2 Cz）及其衍生的聚合物PSCz和PSO 2 Cz。PSCz和PSO 2 Cz的稀溶液通过化学氧化偶联制备的化合物表现出荧光和溶剂变色行为。通过重复循环伏安法扫描单体SCz和SO 2 Cz，可以将聚合物薄膜牢固地电沉积在ITO玻璃基板的表面上在0至1.8V之间的电解质溶液中。由于双咔唑单元的连续氧化，电化学生成的聚合物膜表现出两个可逆的氧化还原对。这些聚合物膜还显示出良好的电化学和电致变色稳定性，其颜色从无色的中性态变为黄色，绿色和蓝色的氧化态。聚合物的转换能力是通过动力学研究评估的，该动力学研究是在其最大对比度下测量透光率百分比（％T）来进行的，表明该聚合物表现出中等的电致变色性能。

  The efficient synthesis and photophysical propel ties of a series of ambipolar donor acceptor donor Systems is described where the acceptor is dibenzothrophene S,S-dioxide and the donor is fluorene, carbazole or arylamine The systems exhibit intramolecular charge transfer (ICT) states (available ICT character strengths)}editing to fluorescence emission ranging from deep blue to green with model ate to high photoluminescence quantum yields The emission properties can be effectively tuned by systematically changing die position of substitution on both donor and acceptor units (which affects the extent of conjugation) and the redox potentials of the donor units The results are supported by cyclic voltammetric data and TD-DFT calculations
