【摘要】：利用斯蒂爾偶聯(lián)反應(yīng)合成了兩種有機(jī)共軛單體,通過電化學(xué)方法聚合成導(dǎo)電聚合物,并對(duì)其進(jìn)行了結(jié)構(gòu)表征和電化學(xué)性能研究。核磁共振1 H譜和13 C譜驗(yàn)證了單體與理論結(jié)構(gòu)一致,紅外測(cè)試驗(yàn)證了電化學(xué)聚合位點(diǎn)為噻吩的α位。在0~1.2V電壓范圍內(nèi),兩種聚合物膜都表現(xiàn)出電致變色特性。相比于聚合物P1,結(jié)合力更強(qiáng)的聚合物P2的電化學(xué)和熱穩(wěn)定性更優(yōu)。結(jié)論表明,苯并硒二唑類聚合物在電致變色領(lǐng)域是一種有前景的材料,單體結(jié)構(gòu)差異對(duì)聚合物性能有很大影響。
[Abstract]:Two kinds of organic conjugated monomers were synthesized by Steele coupling reaction and polymerized into conductive polymers by electrochemical method, and their structure and electrochemical properties were studied. Nuclear magnetic resonance 1H spectra and 13 C spectra confirmed that the monomer was consistent with the theoretical structure, and the electrochemical polymerization site was confirmed to be the 偽 site of thiophene by infrared spectroscopy. In the voltage range of 0 鈮，
