Self-assembly of p-sulfonatocalix[4]arene and a Ag-hmt coordination polymer into a porous structure

A novel porous material constructed from p-sulfonatocalix[4]arene molecules and a Ag-I coordination polymer has been structurally characterized. The porous supramolecular complex features a bilayer arrangement of p-sulfonatocalix[4]arene molecules linked by a Ag-I-hmt (hmt: hexamethylene- tetramine) coordination polymer through metal-ligand bonding, hydrogen bonding and host-guest interactions.
