摘　　要：在溶剂热条件下,利用半刚性咪唑羧酸配体4-(2-甲基咪唑)苯甲酸和金属铜合成了一种新的Cu(I)配位聚合物[Cu(H_(2)O)(MIBA)]n,其中HMIBA代表有机化合物4-(2-甲基咪唑)苯甲酸。在室温条件下,研究了基于半刚性咪唑羧酸配体构筑的Cu(I)有机骨架配位聚合物的固体荧光性能,其中配体HMIBA的最大发射峰为433 nm,配位聚合物[Cu(H_(2)O)(MIBA)]n的最大发射峰为412 nm,均显示出荧光性能。此外,通过X射线单晶衍射仪、红外光谱、热重分析和元素分析对其晶体结构进行了表征。X射线单晶衍射表明,该聚合物呈3D→3D双重互穿网络,具有(64·82)的四连通单节点拓扑结构。Under solvothermal conditions,a new Cu(I)coordination polymer[Cu(H_(2)O)(MIBA)]n was synthesized by using semi-rigid imidazole carboxylic acid ligand 4-(2-methylimidazole)benzoic acid and copper,in which MIBA is the negative monovalent anionic coordination polymer of 4-(2-methylimidazole)benzoic acid.The solid-state fluorescence properties of Cu(I)organic skeleton coordination polymer based on semi-rigid imidazole carboxylic acid ligands were studied at room temperature.The maximum emission peak of MIBA ligand is 433 nm,and the maximum emission peak of coordination polymer[Cu(H_(2)O)(MIBA)]n is 412 nm,all of which show fluorescence properties.In addition,its crystal structure was characterized by X-ray single crystal diffractometer,infrared spectrum,thermogravimetric analysis and elemental analysis.X-ray single crystal diffraction shows that the polymer is a 3D→3D double interpenetrating network with a(64·82)four-connected single-node topology.
