Abstract
Metal-organic frameworks (MOFs) having inorganic nodes that comprise an octahedral Hf6 cluster capped by eight μ3-ligands and having twelve octahedral edges, wherein the μ3-ligands are hydroxo ligands, oxo ligands or aquo ligands; and organic linkers connecting the organic nodes, the organic linkers comprising 1,3,6,8-tetrakis(p-benzoic acid)pyrene units; wherein eight of the twelve octahedral edges of the inorganic nodes are connected to the 1,3,6,8-tetrakis(p-benzoic acid)pyrene units are provided.
