Charged porous organic frameworks containingheteroatoms were synthesized via 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
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Yamamoto 型 Ullmann 偶联反应合成了含有杂原子的带电多孔有机骨架。首次成功地将含硼原子的单体同源耦合以获得 3D 带电多孔有机骨架。多孔有机骨架中的杂原子和电荷有助于增加骨架与气体之间的相互作用。因此,本研究中合成的带有杂原子的带电多孔有机骨架表现出高等量气体吸附焓,超过了许多其他多孔有机材料。
