Structural characterization of crystalline inclusion complexes formed from 1,3,5-triaroylbenzene derivatives—a new family of inclusion hosts

Abstract

A series of crystalline inclusion complexes formed from substituted 1,3,5-triaroylbenzene hosts and small molecule guests has been structurally characterized by X-ray crystallography. The new inclusion hosts examined do not possess functional groups capable of participating in strong non-covalent interactions, thus C–H⋯O hydrogen bonding appears to significantly influence the crystal packing observed in most of the solid state structures. The thermochemical properties of the inclusion complexes were examined using differential scanning calorimetry.
