The supramolecular entities formed by five polybenzimidazolylmethanes,bis(2-tert-butylbenzimidazol-1-yl)methane 2, bis(2-(adamant-1-yl)benzimidazol-1-yl)methane 3, tris(2-ethylbenzimidazol-1-yl)methane 4, tris(2-isopropyl-benzimidazol-1-yl) methane 5, and tris(2-chlorobenzimidazol-1-yl)methane 6 have been investigated. Compounds 2 and 5 crystallize without any included guest, while compounds 3 (methanol and water), 4 (water), and 6 (cyclohexane) show their host properties.
