摘要

A crystallization study of four tetra-O-Alkyl pcarboxylatocalix[4]arenes from a series of pyridine derivatives has been carried out to investigate the effects of varying the length of the calixarene lower-rim alkyl group introduced, and the introduction of alkyl groups around the pyridine guest/ template. Analysis of 11 of 24 possible sets of single crystals formed shows trends in self-Assembly based on the availability of the calixarene cavity for guest/template inclusion, either Py?CO _2H or CO _2H?CO _2H synthons, and dominance of one synthon over the other depending on the position of alkyl groups around the pyridine ring.
