SELF-ASSEMBLED MOLECULAR CAPSULE BASED ON THE HYDROGEN-BONDING INTERACTION BETWEEN 2 DIFFERENT CALIX[4]ARENES

Intermolecularly hydrogen-bonded molecular container constructed from two calix[4]arene derivatives having carboxylic acids (1) or pyridyl groups (2) on their upper rim was designed for the first time. The formation of a simple but very interesting self-assembled molecular capsule was confirmed by physical measurements: i.e., solubility, molecular weight, and fluorescence spectroscopy.
