【摘要】 利用水热法合成了2个新的配位聚合物（CPs）:[M（3,4′-oba）（phen）（H₂O）]_n（M=Zn （1）、Cu （2）,3,4′-H₂oba=3-（4′-羧基-苯氧基）苯甲酸,phen=菲咯啉）,并用X射线单晶衍射测定其晶体结构。CP1为一维链状结构,中心金属Zn²⁺的配位环境为[ZnO₃N₂],形成四方锥构型。配体3,4′-oba以μ₁∶η¹η⁰/μ₁∶η¹η⁰的模式与Zn²⁺配位。CP2中Cu²⁺的配位环境为[CuO₄N₂],呈扭曲的八面体构型。配体3,4′-oba采用μ₁∶η¹η⁰/μ₁∶η¹η¹的模式连接2个Cu²⁺形成一维"之"字链结构。一维链分别通过分子间氢键C—H…O （1）和O—H…O （2）形成二维超分子网状结构。配体phen以双齿螯合的形式与Zn²⁺/Cu²⁺配位。CP1表现出强的荧光,归因于配体的π*-π跃迁。研究了1在不同溶剂中的发光性能以及对镧系金属离子的荧光敏化效果。CP1的荧光被丙酮分子猝灭,而可以敏化稀土金属Tb³⁺离子发出强的绿色荧光,因而1可作为检测丙酮分子和Tb³⁺离子的荧光传感器。更多还原

【Abstract】 Taking 3-（4’-carboxyl-phenyloxy） benzoic acid（3,4’-H₂ oba） and phenanthroline（phen） as ligands,two coordination polymers（CPs） [M（3,4’-oba）（phen）（H₂O）]_n（M=Zn（1）,Cu（2）） were synthesized by hydrothermal method and their structures were characterized by X-ray single crystal diffraction.CP 1 features a one-dimensional chain structure.The coordination environment of Zn²⁺ ion is [ZnO₃N₂],forming tetragonal vertebral configuration.The Zn²⁺ions are linked by 3,4’-oba ligands through μ₁:η¹η⁰/μ₁:η¹η⁰ coordination modes.CP 2 has a structure with [CuO₄N₂]coordination unit.Ligand 3,4’-oba uses the pattern of μ₁:η¹η⁰/μ₁:η¹η¹ to connect two Cu²⁺ to form a 1D zigzag chain structure.The 1D chain forms a 2D supramolecular network structure through hydrogen bonds（C—H…O in 1 and O—H…P in 2）.Ligand phen coordinates with Zn²⁺/Cu²⁺ by bidentate chelation mode.CP 1 showed strong fluorescence,which is attributed to the π^*-π transition of the ligand.The fluorescence properties of 1 in different solvents and the fluorescence sensitization effect on lanthanide metal ion were studied.The fluorescence of CP 1 was quenched by acetone molecule,and it can sensitize the rare earth metal Tb³⁺ ions to emit strong green fluorescence.Therefore,1 can be used as a fluorescence sensor for detecting acetone molecule and Tb³⁺ ion.CCDC:2005286,1;2005285,2.更多还原
