以合成具有荧光性能的配合物为目的,选用了三羧酸类有机配体3-(3-羧基-苯氧基)邻苯二甲酸(H3cppa),与过渡金属Cd(Ⅱ)在水热145℃的条件下合成新颖结构的配合物[Cd(Hcppa)(H_2O)_2(CH_3OH)]_n.配合物通过X射线单晶衍射仪、TGA、FTIR、PXRD、荧光等对配合物的结构及性能进行了表征.分析表明:配位聚合物为一维链状结构,通过分子间弱作用力形成了三维网状结构,具有良好的热稳定性和荧光性能.
For the purpose of synthesizing a fluorescent complex, the tricarboxylic acid organic ligand 3- (3-carboxy-phenoxy) phthalic acid (H3cppa) was chosen to react with the transition metal Cd (Ⅱ) (Cd (Hcppa) (H_2O) _2 (CH_3OH)] _ n. The structure and properties of the complexes were characterized by X-ray single crystal diffraction, TGA, FTIR, PXRD and fluorescence. The results showed that the coordination polymer was a one-dimensional chain structure, which formed a three-dimensional network structure with weak intermolecular force and had good thermal stability and fluorescence.
