A series of metal-organic super-containers (MOSCs) were isolated from the coordination-driven self-assembly of calixarene derivatives, various metal ions and tricarboxylate ligands. The synthesis of MOSCs is highly modular, robust, and predictable. These MOSCs are well characterized by single crystal X-ray diffraction, thermal gravimetric analysis and gas/vapor adsorption. The structural studies show that these MOSCs possess both endo and exo cavities. The gas/vapor adsorption studies on the crystals of MOSCs indicate that the materials are permanently porous, and some of the MOSCs show interesting CO2/N2 selectivity. The unique features of MOSCs are expected to provide new exciting opportunities for the exploration of their functional applications.
