benzene–pyrrole oligomers with diverse functional groups and the elongated alternating heterocycle–benzene–pyrrole oligoaryls. The syntheses are based on a one-pot, three-step reaction of propargylic dithioacetals and imines. The subtle influence of functional groups, such as ether, ester, hydroxy, and dithiacetal groups on the peripheral benzene rings, on the reaction, has been explored and the reaction conditions
交替的苯-杂芳基低聚物具有迷人的光电特性和广泛的应用。本文介绍了具有不同官能团的苯 - 吡咯低聚物和拉长的交替杂环 - 苯 - 吡咯低聚芳基的简便合成。该合成基于炔丙基二硫缩醛和亚胺的一锅三步反应。探索了外围苯环上的醚、酯、羟基和二硫缩醛等官能团对反应的微妙影响,并相应地改变了反应条件以达到合理的收率。伸长可以通过使用类似的程序来完成。确定了原始和延长的交替苯-吡咯低聚物的荧光特性。
