【摘要】：环三磷腈及其衍生物是一类很重要的分子,在超分子化学和材料化学中得到了广泛的应用。然而,关于环三磷腈及其衍生物的MOF材料仍然很少被探索。在本文中,我们设计并合成了三种新颖环三磷腈功能化多羧酸配体,分别是六(3,5-二羧基苯氧基)环三磷腈(H12L)、六(4-羧基苯氧基)环三磷腈(H6L1)和六(3-羧基苯氧基)环三磷腈(H6L2)。并使用它们分别与过渡金属离子、碱土金属离子和稀土金属离子反应,通过溶剂热法合成了12个金属-有机骨架化合物,分别是：[Cu3L(H2O)3]·5DMA·4EtOH·2H2O (L= L1) (1)[Cu3L(H2O)3]·5DMF·2MeOH·2H2O (L= L2) (2)[Cd5L(H2O)4]·2(CH3)2NH2·6DMF (L=L) (3)[Mg3L2(H2O)6]·6(Me2NH2)·DMA·H2O (L=L1) (4)[Ca3L(DMF)2](L=L1)(5)[Ba3L(H2O)4(DMF)]·DMF·2H2O (L=L1) (6)[Sm4L2(CH3COO)(H2O)]·(CH3)2NH2·17DMA (L=L1) (7)[Eu4L2(CH3COO)(H2O)]·(CH3)2NH2·17DMA (L=L1) (8)[Gd4L2(CH3COO)(H2O)]·(CH3)2NH2·13DMA (L=L1) (9)[Tb4L2(CH3COO)(H2O)]·(CH3)2NH2·15DMA (L=L1) (10)[Dy4L2(CH3COO)(H2O)]·(CH3)2NH2·17DMA (L=L1) (11)[Ho4L2(CH3COO)(H2O)]·(CH3)2NH2·20DNA (L=L1) (12)对合成的配合物进行单晶结构分析和常规表征,并研究了其中几个配合物在气体吸附分离和荧光检测方面的应用。
