New host molecules, 1(a, b) and 2(a, b), each containing two bulky borneol or fenchol terminal groups attached to ethynylene central units of different lengths, have been synthesized. Their properties of crystalline inclusion with a variety of organic guests, including alcohols, amines and dipolar aprotic compounds, are reported (26 examples of inclusion compounds). The crystal structures of four selected inclusion compounds have been determined by X-ray diffraction, showing varied modes of supramolecular interaction dependent on the host and guest constitutions. Varying stoichiometries, host-guest compositions and appearance of disorder all indicate match/mismatch phenomena in the molecular recognition process under the build-up of macroscopic crystals. All these crystalline associations are organized through the hydrogen bonding capability of the host hydroxyl groups, thus corresponding to coordinato-clathrate scenery.
