文摘

A new metal–organic framework {[Zn2(bpta)(bpy-ee)(H2O)2]·x solve}n (1) (H4bpta = biphenyl-2,2′,6,6′-tetracarboxylic acid and bpy-ee = 1,2-bis(4-pyridyl)ethylene) has been obtained under hydrothermal condition, and structurally characterized by single-crystal X-ray diffraction. Complex 1 reveals a three-dimensional (3D) “pillar-layered” framework with non-flexible linker, in which some different structure characters can be found compared to that of some related other “pillar-layered” MOFs based on flexible pillar linkers. It demonstrates the impact of the flexibility of pillar linker on the final structure in this system. In addition, the selective CO2 adsorption performance of 1 was also investigated.
