Abstract
A chiral calix[4]arene bearing l-2,3-dibenzoyltartaric acid groups at the lower rim was synthesized and could enantioselectively self-assemble to result in a gel or suspension only with one enantiomer of chiral amines; as revealed by electron microscopy, the resultant gel was of nanofibers with a high aspect ratio but the suspension was composed of nanospheres.
摘要
一种在下缘带有L-2,3-二苯甲酰基酒石酸基团的手性杯[4]芳烃被合成出来，它能够对映选择性地自组装，仅与手性胺的一种对映体形成凝胶或悬浮液；电子显微镜显示，所得凝胶由高纵横比的纳米纤维组成，而悬浮液则由纳米球组成。
