Ultramicroporous metal-organic framework based on 9,10-anthracenedicarboxylate for selective gas adsorption.

An ultramicroporous metal-organic framework based on 9,10-anthracenedicarboxylate (PCN-13) has been synthesized and structurally characterized. The desolvated PCN-13 demonstrates selective adsorption of oxygen and hydrogen over nitrogen and carbon monoxide.

Metal-organic framework based on a trinickel secondary building unit exhibiting gas-sorption hysteresis.

An interpenetrating microporous metal-organic framework based on a mu3-oxotrinickel basic carboxylate secondary building unit has been synthesized and structurally characterized. It exhibits pronounced gas-sorption hysteresis and selective adsorption of carbon dioxide over methane.
