以苯并噻二唑为初始原料,通过硝化、还原、缩舍等反应合成了2种新型单体5,10-二溴-2,3,7,8-二萘基双喹喔啉(M1)和5,10-二溴-2,3,7,8-二菲基双喹喔啉(M2).2种单体分别与1,4-二炔基-2,5-二氧十二烷基苯共聚,得到了2种新型共轭共聚物,聚(2,3,7,8-二萘基双喹喔啉-二炔基--2,5-二氧十二烷基苯)(P1)(产率86.1％)和聚(2,3,7,8-二菲基双喹喔啉-二炔基-2,5-二氧十二烷基苯)(P2)(产率41.6％).所得单体通过红外光谱、棱磁共振等进行了表征.单体和聚合物的紫外-可见吸收光谱中M1的最大吸收波长在339 nm,354 nm处出现.M2的最大吸收波长分别在304 nm,317 nm处出现双吸收峰外,在长波431 nm,459 nm处出现双吸收峰.P1的最大吸收波长在448 nm处出现,在305 nm和317 nm处出现2个吸收峰.P2在短波处吸收峰分别在350 nm,368 nm处出现.单体荧光光谱图中分别在480 nm和579 nm出现最大发射峰.聚合物分别在487 nm和478 nm处出现最大发射峰.得到的共聚物通过X射线衍射发现结晶性较差.
