标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M
权利人:EXXONMOBIL RES & ENG CO
摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

摘要:A method for enhancing the conductivity of MOF-5 by the development of an MOF-5 polymer composite material. The composite material incorporates a conductive polymer, preferably polyaniline, in the solvo-thermal synthesis pathway of MOF-5. The electrically conductive MOF-5 composite exhibits electric conductivity three orders of magnitude higher than that of MOF-5 while maintaining the crystallinity, robustness, and thermal stability of MOF-5.
