Abstract

We developed a self-organized monomeric molecular container 3 based on two pairs of intramolecular hydrogen bonds between adjacent carboxylic acid moieties on the upper rim of the cavitand 1. The formation of the molecular container was confirmed by inclusion phenomena of Li+ ina mixture of CDCl3 and C6D6. The lid formed by two pairs of intramolecular hydrogen bonds can be opened in polar solvents such as CD3CN andthe encapsulated guest was subsequently released. All these phenomenawere elucidated by H-1 NMR spectroscopy, MALDI mass spectrometry, vapor pressure osmometry, and molecular modelling studies. (C) 1997 Elsevier Science Ltd.
