1. A method for making a metal organic framework suspension comprising
providing a hybrid material comprising a nano-crystalline metal organic framework comprising micropores and a mesoporous polymeric material comprising mesopores, wherein the nano-crystalline metal organic framework is homogeneously dispersed and substantially present only within the mesopores or void spaces of the mesoporous polymeric material; and wherein the hybrid material has a weight percentage of the metal organic framework in the range of 5-50% relative to the total weight of the hybrid material; and
contacting the hybrid material with a solvent in which the mesoporous polymeric material is soluble, thereby forming a polymeric solution in which the nano- crystalline metal organic framework is substantially homogeneously dispersed and suspended.
