metathesis polymerization to prepare poly(3‐hexylthiophene)‐based copolymers containing electron‐withdrawing 4‐tert‐butylphenyl‐1,3,4‐oxadiazole‐phenyl moieties as side chains. We characterized these copolymers using 1H and 13C nuclear magnetic resonance spectroscopy, thermogravimetric analysis, and gel permeation chromatography. The band gap energy of copolymer was determined from the onset of the
我们已经使用格利雅(Grignard)复分解聚合反应制备了基于聚(3-己基噻吩)的共聚物,该共聚物含有吸电子的4-叔丁基苯基-1,3,4-恶二唑苯基部分作为侧链。我们使用1 H和13表征了这些共聚物C核磁共振波谱,热重分析和凝胶渗透色谱。共聚物的带隙能由光吸收的开始确定。在共聚物的光致发光光谱中观察到了淬灭作用,该共聚物在侧链上结合了电子侧链缺失的1,3,4-恶二唑部分。在存在最适量的1,3,4-恶二唑部分的情况下,器件的光电流得以增强,从而提高了功率转换效率。©2010 Wiley Periodicals,Inc.
