An amino-functionalized doubly interpenetrated microporous zinc metal-organic framework (UPC-30) has been solvothermally synthesized. UPC-30 can be stable at 190 degrees C and confirmed by powder X-ray diffraction. Gas adsorption measurements indicate that UPC-30 exhibits high H-2 adsorption heat and CO2/CH4 separation efficiency. After the exchange of Me2NH2+ by Li+ in the channels, the H-2 adsorption heat increased by 19.7%. Because of the existence of -NH2 groups in the channels, UPC-30 can effectively catalyze Knoevenagel condensation reactions with high yield and pore-size-dependent selectivity.
