A supramolecular organic framework, P5-bpy-SOF, made of perhydroxyl-pillar[5]arene (P5) and 4,4-bipyridine (bpy) and prepared by using a co-crystallization approach, showed a different hydrogen bonding pattern and a 3D molecular arrangement from that in the perhydroxyl-pillar[5]arene-based supramolecular organic framework (P5-SOF). TGA analyses, powder X-ray diffraction and gas absorption study confirmed P5-bpy-SOF's structural stability, permanent porosity, and, especially, selectivity of absorption of CO₂ over N₂.

通过共结晶法工程化基于支柱[5]芳烃的超分子有机骨架†

超分子有机骨架P5-bpy-SOF由全羟基-立柱[5]芳烃（P5）和4,4-联吡啶（bpy）制成，并采用共结晶方法制备，显示出不同的氢键模式和3D分子排列，来自基于全羟基柱[5]芳烃的超分子有机骨架（P5-SOF）。TGA分析，粉末X射线衍射和气体吸收研究证实了P5-bpy-SOF的结构稳定性，永久孔隙率，尤其是在N ₂上吸收CO _2的选择性。
