Isoreticular metal-organic frameworks, process for forming the same, and systematic design of pore size and functionality therein, with application for gas storage

The ability to design and construct solid-state materials with pre-determined structures is a grand challenge in chemistry. An inventive strategy based on reticulating metal ions and organic carboxylate links into extended networks has been advanced to a point that has allowed the design of porous structures in which pore size and functionality can be varied systematically. MOF-5, a prototype of a new class of porous materials and one that is constructed from octahedral Zn—O—C clusters and benzene links, was used to demonstrate that its 3-D porous system can be functionalized with the organic groups, —Br, —NH2, —OC3H7, —OC5H11, —H4C2, and —H4C4, and its pore size expanded with the long molecular struts biphenyl, tetrahydropyrene, pyrene, and terphenyl. The ability to direct the formation of the octahedral clusters in the presence of a desired carboxylate link is an essential feature of this strategy, which resulted in the design of an isoreticular (having the same framework topology) series of sixteen well-defined materials whose crystals have open space representing up to 91.1% of the crystal volume, and homogeneous periodic pores that can be incrementally varied from 3.8 to 28.8 angstroms. Unlike the unpredictable nature of zeolite and other molecular sieve syntheses, the deliberate control exercised at the molecular level in the design of these crystals is expected to have tremendous implications on materials properties and future technologies. Indeed, data indicate that members of this series represent the first monocrystalline mesoporous organic / inorganic frameworks, and exhibit the highest capacity for methane storage (155 cm3 / cm3 at 36 atm) and the lowest densities (0.41 to 0.21 g / cm3) attained to date for any crystalline material at room temperature.

Zeolite-like metal organic frameworks (ZMOFS): modular approach to the synthesis of organic-inorganic hybrid porous materials having a zeolite like topology

The subject invention pertains to metal organic frameworks (MOF) having zeolite-net-like topology, their methods of use, and their modes of synthesis. The ZMOFs are produced by combining predesigned tetrahedral building, generated in situ using heterochelation, with polyfunctional ligands that have the commensurate angle and the required donor groups for the chelation. Each molecular building block is contrasted of a single metal ion and ligands with both heterochelation functionality and bridging functionality. Advantageously, zeolite-net-like MOFs of the subject invention are porous and contain large functional cavities, which is useful for encapsulating large molecules.
