Heat-set gels and egg-like vesicles using two component gel system based on chiral calix[4]arenes

Chem Commun (Camb). 2007 Dec 28:(48):5200-2. doi: 10.1039/b713548c. Epub 2007 Oct 12.

Abstract

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.
