| 摘 要： | 利用水热法合成了一种新颖的二维层状结构的配位聚合物Eu(PCPOA)3(H2O)]n(PCPOA-p-chlorophenoxyacetate,对氯苯氧乙酸).在结构测定的基础上,分别开展了磁微扰下的二维相关红外光谱和温度微扰下的二维相关荧光光谱等的研究.采用Material studio的CASTEP程序进行了量子化学的能带分析,探讨了其结构与性能的关系.配合物的中心离子Eu3 处于9配位的环境中,对氯苯氧乙酸的羧酸根离子分别以单齿桥氧,双齿螯合等方式与磁性Eu3 配位.二维相关红外光谱研究表明羧基振动对磁微扰有很强的响应.二维相关荧光光谱研究表明,配合物中Eu3-的5Do→F2跃迁对温度的影响最敏感.

| Abstract: | A novel two dimensional coordination polymer Eu(PCPOA)3 (H2O)], was synthesized under hydrothermal condition. Based on the determination of the structure, the 2D correlation FTIR spectra with the perturbation of magnetism and the 2D correlation fluorescence spectra with the perturbation of temperature were investigated. The energy bonds were calculated using CASTEP Program of Material studio. The Europium ions are nine-coordinated and the ligands adopted two different modes to connect the Eu3+ ions to 2D layer structure. The study of the 2D-FTIR reveals that the carboxylates coordinate with the center ions not only as monodentate, but also as bidentate chelate. The 2D fluorescence spectra indicates that the transition of (5)D0-->(7)F2 is influenced intensively by the perturbation of temperature. |
