Abstract: Metal–organic frameworks (MOFs) are coordination polymers and have been widely studied over the past decade for their potential applications.1–3 By bridging metal centres with appropriate polyfunctional organic linkers, MOF materials can incorporate both high internal surface area and tunable pore size and shape, which offer great promise for gas storage and separation applications.4–8 The strategy of metal cluster units and elongated organic ligands is an effective route to stable MOFs with highly porous framework structures.9,10 A series of Cu(II)-carboxylate MOFs has been reported with organic linkers incorporating tetracarboxylate and hexacarboxylate groups, and the desolvated materials show impressive H2storage capacities,11–14 for the construction of porous MOF materials.15 We report herein the design of a new tetrahedrally-branched octacarboxylate ligand (H8L, Scheme 1) and the preparation of a robust and highly porous metal–organic polyhedral framework NOTT-140 incorporating an aromatic-rich cage structure.
