A series of novel chiral propene oxides bearing substituted N,N-diphenylamino moiety were synthesized and anionically polymerized. Most of propene oxides gave polymers possessing high specific rotation and intensive circular dichroism (CD) signals, which were attributed to the helical conformation of the main chain. Poly(3-(4,4′-dimethoxy)diphenylaminopropene oxide) exhibited the highest specific rotation ([α ]36520 = −5400).
合成了一系列具有取代N,N-二苯胺基团的新型手性丙烯氧化物,并进行了阴离子聚合。大多数丙烯氧化物生成的聚合物具有高的比旋光度和强烈的圆二色性(CD)信号,这归因于主链的螺旋构象。聚(3-(4,4′-二甲氧基)二苯胺基丙烯氧化物)表现出最高的比旋光度([α ]36520 = -5400)。
