Abstract: The synthesis of a novel host blocked in the cone conformation and bearing m-methoxycarbonylbenzyl groups at the lower rim is described. X-ray crystal structure analysis revealed that action of one molecule of compound upon one molecule of CH3CN or one molecule of CH3NO2, forms an intramolecular inclusion complex, respectively, by CH3-π interactions. The complex of L with tetrabutyl ammonium bromide(TBAB), L·TBAB, was obtained. The results of DTA-TG and XRD analysis of L·TBAB can also be considered as an intramolecular inclusion complex.
