features. UV–visible absorption spectra of the polymers showed two strong absorption bands in the ranges 315–370 nm and 450–500 nm, which arose from absorptions of the phenothiazine segments and the conjugated main chains. Solution‐processed field‐effect transistors fabricated from these polymers showed p‐type organic thin‐film transistor characteristics. The field‐effect mobilities of P1, P2, and P3
一系列新的基于碳酸亚乙烯phenothiazylene半导体聚合物,聚[3,7-(4'-十二烷氧基)phenothiazylene乙炔](P1),聚[3,7-(4'-十二烷氧基)phenothiazylene vinylene- ALT -1,4-亚苯基乙烯撑](P2),和聚[3,7-(4'-十二烷氧基)phenothiazylene vinylene- ALT -2,5-亚噻吩基亚乙烯基](P3),都通过Horner-Emmons反应被合成。FTIR和1个1 H NMR光谱证实,在聚合物中的亚乙烯基的结构是所有-反式(É)。P1的重均分子量(M w),发现P2和P3分别为27,000、22,000和29,000,多分散指数分别为1.91、2.05和2.25。P1,P2和P3的热谱图分别仅包含一个宽的玻璃化转变温度,分别在129、167和155°C,而没有观察到熔融特征。聚合物的紫外可见吸收光谱显示在315–370
