Abstract

The aqueous solution reaction of chelidamic acid (H3CAM), succinic acid, CdCl2·2.5H2O in the air at 50 °C, along with little of ammonia added dropwise, gave rise to colorless crystals {Cd2.5(CAM)(HCAM)(H2O)7·1.5H2O}n (1), which presents an interesting (4,6)-connected 3D structure. Notably, 1 is the third homonuclear 3D framework based on H3CAM ligand, which acts as two different μ4/μ5-bridges in 1 and was abbreviated to HCAM2  and CAM3 , respectively, in writing molecular formula of 1. Polymer 1 exhibits strong blue photoluminescence at room temperature.

基于螯合酸的新型(4,6)连接三维金属-有机骨架:合成、晶体结构和光致发光
在空气中,在50℃条件下,螯合酸(H3CAM)、琥珀酸、CdCl2·2.5H2O的水溶液中,随着少量氨的滴入,生成了无色晶体{Cd2.5(CAM)(HCAM)(H2O)7·1.5H2O}n(1),呈现出有趣的(4,6)连接的三维结构。值得注意的是,1是基于H3CAM配体的第三个同核三维框架,在1中充当两个不同的μ4/μ5桥,分别缩写为HCAM2−和CAM3−,写成分子式1。聚合物1在室温下表现出强烈的蓝色光致发光。
