摘要
通过Heck偶联法制备了一种新型聚噻吩衍生物——2,5-二乙烯基-3,4-二辛基噻吩-共-2,5-二苯基-1,3,4-二噁唑(PO2TV-OXD),用核磁共振氢谱(1H NMR)及凝胶色谱(GPC)对其结构进行分析和表征。用紫外-可见光谱(UV-Vis)、荧光光谱(PL)及电化学分析研究其光学和电化学性能,并与3,4-二辛基噻吩均聚物(PO2T)进行了对比研究。研究表明:主链上引入吸电子能力较强的1,3,4-二噁唑基团,明显增加了聚合物的能隙,提高了聚合物的荧光量子效率。
A novel polythiophene derivative ： poly 1- （2,5-bisvinyl-3,4-dioetylthiophene）-alt-2,5- bisphenyl-l,3,4-oxadiazole-] （POzTV-OXD）） was obtained with the method of Heck coupling. The structure was effectively characterized using 1H NMR and GPC. The optical and electrochemical properties were studied by UV-Vis, fluorescence spectroscopy,and cyclic voltammetry and compared with poly （3,4-dioctylthiophene） （PO2T）. The introduction of the 1,3,4- oxadiazole in conjugated chain can increase the bang gap energy and the PL quantum yield.
