Abstract

Two novel Zn(II) metal–organic frameworks (MOFs) constructed by trinuclear-triangular and paddle-wheel units, namely {[Zn5(dmtrz)3(IPA)3(OH)]·DMF·H2O}n (MAC-4, Hdmtrz = 3,5-dimethyl-1H-1,2,4-triazole, H2IPA = isophthalic acid, DMF = dimethyl formamide) and {[Zn5(dmtrz)3(OH-IPA)3(OH)]·DMF·5H2O}n (MAC-4-OH, OH-H2IPA = 5-hydroxyisophthalic acid), were solvothermally synthesized. Single-crystal analyses reveal that MAC-4-OH is an iso-reticular framework of MAC-4 with channels functionalized by hydroxyl groups. Gas adsorption reveals that MAC-4-OH shows a significant enhancement for CO2 uptake compared with that of MAC-4 due to the existence of electrostatic attractive interactions, though its surface area is lower than that of MAC-4.
