手性杯[4]芳烃在上边缘带有长的叔烷基基团，在下边缘带有S-1-苯乙胺基团，可以在环己烷中与d-2，3-二苯甲酰基酒石酸对映选择性地形成热固化凝胶和蛋形囊泡，这是由两种组分胶凝剂之间的相互作用差异导致的热固化凝胶的第一个例子：另外，随着烷基长度的增加，囊泡的直径减小，这可以用来控制囊泡的大小。
Chiral calix[4]arenes bearing long tertiary alkyl groups at the upper rim and S-1-phenylethylamine groups at the lower rim can form heat-set gels and egg-like vesicles enantioselectively with d-2,3-dibenzoyltartaric acid in cyclohexane, which is the first example of heat-set gels resulting from difference in interactions between two component gelators: in addition, the diameter of vesicles decreased with the increase in length of alkyl groups, which could be used to control the size of the vesicles.
