Complex mixed ligand open framework materials

A porous multi-variate metal organic framework (mvMOF) comprising a plurality of linking moieties comprising one or more functional groups, wherein the functional groups between at least two or more linking moieties are non-uniform, and wherein the functional groups of one or more linking moieties do not adversely effect the connectivity or spatial orientation of the linking clusters to one or more metals or metal ions, and wherein the functional groups modify the chemical and physical properties of a pore in the framework.
