在水热条件下合成了一种新的金属有机骨架化合物{[Zn 2（bpta）（bpy-ee）（H2O）2]·xsolve}n（1）（H4 bpta =联苯-2，2 ′，6，6 ′-四羧酸，bpy-ee = 1，2-二（4-吡啶基）乙烯），并通过单晶X射线衍射对其结构进行了表征.配合物1显示了一个具有非柔性连接基团的三维“柱层状”结构，与其他一些基于柔性柱连接基团的“柱层状”结构相比，具有一些不同的结构特征。它展示了柱连接体的柔性对该系统中最终结构的影响。此外，还考察了1对CO2的选择性吸附性能。
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. Complex1reveals 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 CO2adsorption performance of1was also investigated.
