Abstract

Calixarene-based functional assemblies having potential for metal ion and/or molecular recognition were obtained: they are (1) gelators and (2) polymers. Calix[n]arenes bearing aliphatic chains at the p-position (2nCm, n = 4, 6, and 8; m = 6, 12, and 18) have been synthesized by direct acylation from calix[n]arenes (1n) and serve as novel gelators of organic fluids. It has been established that the gelation process is thermally reversible, and the formation mechanism of the gels is ascribed to C=0. •. HO hydrogen bonding. On the other hand, insoluble polymer gels could also be obtained from a mixture of monovinyl- and divinyl-calix[4]arenes and they showed ion-selective swelling.
