基于超分子构筑模块和酰胺插入的螺旋配体的PCN类型金属有机骨架的结构和选择性吸附CO2 |
PCN-Type Metal-Organic Framework Based on Amide-Inserted Helical Ligand and Supramolecular Building Blocks: Structure and CO2 Selective Adsorption |
|
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 (H4L)的链接,形成了一个pcu拓扑的微孔金属有机骨架[Cu2(L)(H2O)2]·DMF·6H2O(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。 |

Abstract: 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 (H4L) for the first time, and a microporous metal-organic framework (MOF) [Cu2(L)(H2O)2]·DMF·6H2O (NTUniv-53) with pcu topology was formed. The synthesized NTUniv-53 showed a noticeable CO2 selective adsorption at room tempera-ture, which was insensitive to temperature change due to the narrowed windows and amide groups. |
Keywords: metal-organic frameworks CO2 adsorption amide selectivity |
