Thiacalix[4]arene-alkali metal assemblies: crystal structures and guest-binding capabilities of supramolecular architectures supported by metal coordination and cation-π interactions

Single-crystal X-ray diffraction study of p-H-thiacalix[4]arene as a cesium complex demonstrated that a supramolecular architecture is constructed by intra- and inter-molecular interactions, such as metal coordination, aromatic-H⋯S hydrogen bonding, and alkali metal cation-π interaction. On the guest-binding behaviors of two complexes toward three alcohol molecules, the complexes exhibited a high adsorption capability toward ethanol molecule.
