Patent ID: 6930193

Claim:
A systematically formed isoreticular metal-organic framework (IRMOF), consisting essentially of: a plurality of secondary building units (SBUs), each of the plurality of SBUs comprising an M 4 O(CO 2 ) 6 cluster; and a compound linking adjacent SBUS, the linking compound comprising a linear ditopic carboxylate having at least one substituted phenyl group and at least one functional group X attached to the at least one substituted phenyl group; wherein the IRMOF has a substantially permanent porosity and is substantially stable; wherein the functional group X is at least one of hydrogen, amines, halides, an R group selected from at least one of linear, substituted or cyclo alkanes, alkenes, alkynes, chains, and ether O—R, wherein R is at least one of linear, substituted or cyclo alkanes, alkenes, alkynes, chains, and mixtures thereof; and M is a metal cation; and wherein at least one of functionality, dimension, pore size and free volume of the IRMOF is substantially determined by the linking compound.
