| 摘要: | 摘要： Six 2D metal–organic frameworks containing V-shaped 4,4′-sulfonyldibenzoate (SBA) linkers, [Zn 3 (SBA) 2 (OH) 2 ]·EtOH ( 1 or CYCU-5 ·EtOH), [M 3 (OH) 2 (SBA) 2 (EtOH)(H 2 O) 3 ]·3.5H 2 O ( 2–4 , M = Mg, Ni, and Co), [Mn(SBA)(EtOH)] ( 5 ) and [Mn(SBA)(H 2 O)] ( 6 ), have been synthesized rapidly under microwave-assisted solvothermal conditions. The structural analysis revealed that all compounds display two-dimensional structures containing inorganic motifs with one-dimensional chains ( 1–5 ) or dimers of trigonal prisms ( 6 ) connected through SBA linkers and forming 2D neutral and porous channels. Compounds 1–4 were further characterized by elemental analysis, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) measurements and IR spectroscopy. The desolvated phases of compounds 1–2 / 3–4 have thermal stabilities up to about 400/350 °C. The desolvated frameworks of 1–4 above 200 °C have similar CYCU-5 -like conformations and exhibit gas adsorption properties with N 2 , CO 2 and H 2 gases. Interestingly, CYCU-5 displays selective adsorption of CO 2 over N 2 and CH 4 gases at 273 K. In addition, the catalytic ability of CYCU-5 as an initiator for ring-opening polymerization of l -lactide has also been demonstrated.
