摘　　要：首次实现了窗口缩小的小斜方六面体超分子构筑模块(SBB)和酰胺功能化螺旋配体5,5′-(((1,1′-biphenyl)-2,2′-dicarbonyl)bis(azanediyl))diisophthalic acid(H_(4)L)的链接,形成了一个pcu拓扑的微孔金属有机骨架[Cu_(2)(L)(H_(2)O)_(2)]·DMF·6H_(2)O(NTUniv-53),其在室温下展示了良好的二氧化碳吸附选择性。由于窗口缩小和酰胺的共同作用,该选择性基本不受温度变化的影响。A small rhombohedral supramolecular building block(SBB)with a narrowed window was linked with amide-functionalized helical ligand 5,5′-(((1,1′-biphenyl)-2,2′-dicarbonyl)bis(azanediyl))diisophthalic acid(H_(4)L)for the first time,and a microporous metal-organic framework(MOF)[Cu_(2)(L)(H_(2)O)_(2)]·DMF·6H_(2)O(NTUniv-53)with pcu topology was formed.The synthesized NTUniv-53 showed a noticeable CO_(2) selective adsorption at room temperature,which was insensitive to temperature change due to the narrowed windows and amide groups.CCDC:2095677.
