A barium(II) metal‐organic framework (MOF) based on a predesigned amino‐functionalized ligand, namely [Ba2(L)(DMF)(H2O)(NO3)1/3]⋅DMF⋅EtOH⋅2 H2O (UPC‐33) [H3L=4,4′‐((2‐amino‐5‐carboxy‐1,3‐phenylene)bis(ethyne‐2,1‐diyl))dibenzoic acid] has been synthesized. UPC‐33 is a 3‐dimensional 3,18‐connected network with fcu topology with a rare twelve‐nuclear Ba12(COO)18(NO3)2 cluster. UPC‐33 shows permanent porosity and a high adsorption heat of CO2 (49.92 kJ mol−1), which can be used as a platform for selective adsorption of CO2/CH4 (8.09). In addition, UPC‐33 exhibits high separation selectivity for C3 light hydrocarbons with respect to CH4 (228.34, 151.40 for C3H6/CH4, C3H8/CH4 at 273k and 1 bar), as shown by single component gas sorption and selectivity calculations. Due to the existence of −NH2 groups in the channels, UPC‐33 can effectively catalyze Knoevenagel condensation reactions with high yield, and substrate size and electron dependency.

基于稀有Ba12(COO)18(NO3)2簇的氨基官能化金属有机骨架,可有效分离C3 / C2 / C1,并具有良好的催化性能
基于预先设计的氨基官能化配体的钡(II)金属有机骨架(MOF),即[Ba 2(L)(DMF)(H 2 O)(NO 3)1/3 ] · DMF · EtOH · 2 H 2 O(UPC-33)[H 3 L = 4,4'-(((2-氨基-5-羧基-1,3-亚苯基)双(乙炔-2,1-二基))二苯甲酸]合成的。UPC-33是具有fcu拓扑的3维3,18连接网络,具有罕见的十二核Ba 12(COO)18(NO 3)2簇。UPC-33表现出永久的孔隙率和很高的CO 2吸附热(49.92 kJ mol-1),其可用作选择性吸附CO 2 / CH 4(8.09)的平台。此外,UPC-33对CH 3相对于CH 4表现出对C 3轻烃的高分离选择性(在273k和1 bar下C 3 H 6 / CH 4,C 3 H 8 / CH 4的228.34、151.40),如图所示。单组分气体吸附和选择性计算。由于通道中存在-NH 2基团,UPC-33可以高效催化Knoevenagel缩合反应,并具有高产率,底物尺寸和电子依赖性。
