Abstract

Conformational properties of several mono-alkyl ester derivatives of p-tert-butylcalix[6]arene depending on temperatures have been investigated by solution NMR spectroscopy. It is found out that all derivatives can adopt a cone-like conformation around room temperature, while the conformational characteristics at high temperatures seem to be quite different each other.
