1. A composition comprising:
a mesoporous metal-organic framework (MOF) having at least one nanoscopic cage, wherein at least one nanoscopic cage includes a biomolecule, wherein the biomolecule is myoglobin or is selected from the group consisting of: microperoxidase, alcohol dehydrogenase, α-amylase, chloroperoxidase, α-chymotrypsin, glucose oxidase, horseradish peroxidase, laccase, lipase, manganese peroxidase, soybean peroxidase, trypsin, glycosylase, lysozyme, and a combination thereof, wherein the MOFs are coordination polymers with an inorganic-organic hybrid frame comprising metal ions or clusters of metal ions and organic ligands coordinated with the metal ions and/or clusters, wherein the MOFs are organized in a one-, two- or three-dimensional frameworks in which the metal clusters are linked to one another periodically by bridging ligands, pillar ligands, or a combination thereof, wherein the metal ions are selected from the group consisting of: Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, Ga, In, Tl, Si, Ge, Sn, Pb, As, Sb, Bi, or di-metals thereof, wherein the metal ion has a 1+, 2+, 3+, 4+, 5+, 6+, 7+, or 8+ charge, wherein the bridging ligands and the pillar ligands include one or more functional groups that coordinate with the metal(s), link metal containing groups, or both, wherein the functional group is selected from the group consisting of —CO2H, —CS2H, —NO2, —B(OH)2, and —SO3H, wherein the functional groups are bonded to the organic compound so to from the coordinative bond and of producing the framework material of the MOF, wherein the organic compound is selected from the group consisting of a polycarboxylated ligand, a polypyridyl ligand, a polycyano ligand, a polyphosphonate ligand, a polyhydroxyl ligand, a polysulfonate ligand, a polyimidazolate, ligand, a polytriazolate (both 1,2,3 and 1,2,4) ligand, polytetrazolate ligand, polypyrazolate ligand, and mixtures and combinations thereof. |
