摘    要:
用天然酒石酸与不同芳香二胺成盐后,经高温缩聚反应,合成了五种新的旋光性聚酰胺,讨论了聚合条件对聚合物的[α]_D~(20)值的影响以及聚合物的旋光稳定性、热稳定性。~1H-NMR及园二色(CD)谱显示聚合物的分子链存在某种有序构象。手性拆分实验初步显示所合成的聚酰胺对苯丙氨酸有手性识别能力。

关 键 词:旋光性聚酰胺 缩聚反应 有序构象

Abstract:
Five new optically active polyamidcs were synthesized at high temperatures by the condensation of the salts from L-tartaric acid with diamincs. The influence of polymerization condition on the specific rotation was discussed. Based on the specific rotation,'H-NMR, CD, IR, these polyamides were found to exist in ordered conformation other than one-handed helix. Moreover, the ordered conformation was quite stable according to the plot of specific rotation versus tempertature. The primary investigation showed polyamides could discriminate the racemates of phenylalanine.
Keywords:optically active polyamides   high temperature polycondensation   ordered conformation   chiral recognition ability.
