The functionalization and modification of the ligand 1,3,5-tris(4-carboxyphenyl)benzene (H3BTB) have been realized with amine (NH2-H3BTB) and hydroxy (HO-H3BTB) groups. Three new Cd(II) compounds based on R-H3BTB ligands (R = âNH2 and âOH) have been synthesized and structurally characterized. Compounds 1 and 2 show pillared-layer frameworks and display strong fluorescence emission ability. Compound 3 features a 3D porous framework with trinuclear Cd units linked by the NH2-BTB ligand. The activated framework of 3 has good gas storage and separation properties for CO2 and hydrocarbons.
配体1,3,5-三(4-羧基苯基)苯(H3BTB)的官能化和修饰已通过胺基(NH2-H3BTB)和羟基(HO-H3BTB)实现。合成了三种基于 R-H3BTB 配体(R = -NH2 和 -OH)的新 Cd(II) 化合物并进行了结构表征。化合物1和2显示出柱层框架并表现出很强的荧光发射能力。化合物 3 具有 3D 多孔框架,其中三核 Cd 单元通过 NH2-BTB 配体连接。 3的活化骨架对CO2和碳氢化合物具有良好的气体储存和分离性能。
