Charged porous organic frameworks containing heteroatoms were synthesized a Yamamoto-type Ullmann coupling reaction using potassium tetrakis(4-bromopyrazolyl)borate and tetrakis(4-chlorophenyl)phosphonium bromide as monomers. For the first time, a monomer containing boron atoms was successfully homocoupled to obtain a 3D charged porous organic framework. The heteroatoms and charges in the porous organic frameworks help to increase the interaction between the frameworks and the gases. Therefore the charged porous organic frameworks bearing heteroatoms synthesized in the present study exhibit high isosteric enthalpies of gas adsorption which surpass those of many other porous organic materials.
使用四（4-溴吡唑基）硼酸钾和四（4-氯苯基）溴化鏻作为单体，通过山本型乌尔曼偶联反应合成了含杂原子的带电多孔有机框架。首次成功地将含硼原子的单体进行了均偶联，从而得到了一种三维带电多孔有机框架。多孔有机框架中的杂原子和电荷有助于增强框架与气体之间的相互作用。因此，本研究中合成的含杂原子的带电多孔有机框架表现出较高的气体吸附等焓，超过了许多其他多孔有机材料。
