A flexible metal–organic framework (MOF) [Mn(INA)₂]·MeOH (1) (INA⁻ = isonicotinate) has been solvothermally synthesized. Single-crystal X-ray diffraction reveals that compound 1 features a 3D microporous framework containing one-dimensional channels. The activated phase 1a displays permanent porosity with a Brunauer–Emmett–Teller (BET) surface area of 236 m² g⁻¹. Gas sorption analyses reveal that 1a exhibits interesting gate-opening hydrocarbon sorption behavior with considerable C2 uptake capacities but a negligible amount for CH₄ under ambient conditions. Selectivity calculation and breakthrough experiment comprehensively demonstrate that 1a has remarkably high selectivity towards C2 hydrocarbons over CH₄ under ambient conditions.

通过微孔金属-有机骨架中的开门作用分离C2 / C1碳氢化合物

柔性金属-有机骨架（MOF）[锰（INA）₂ ]·甲醇（1）（INA ^- =异烟酸甲酯）已经被溶剂热合成。单晶X射线衍射揭示化合物1具有包含一维通道的3D微孔骨架。活化相1a的永久孔隙度为Brunauer-Emmett-Teller（BET）表面积为236 m ² g ^-1。气体吸附分析表明1a表现出有趣的开门碳氢化合物吸附行为，具有相当大的C2吸收能力，但CH _4的量可忽略不计在环境条件下。选择性计算和突破实验综合表明，在环境条件下1a对CH _4而言对C2烃具有极高的选择性。
