摘要
文制备了三种同构镧系金属有机框架材料(Me2NH2)[Ln2L2(NO3)-OH)(H2O)]·2H2O·2DMA, (Ln = Eu(1), Gd(2) and Tb(3), H2L =9-甲基-9-羟基-2,7-芴二羧酸, DMA = 二甲基乙酰胺). 研究结果显示它们具有三维阴离子型框架结构, 该结构可简化为含有单一的8连接型节点的体心立方(bcu)型拓扑结构. 化合物1表现出基于配体的荧光发射峰以及铕离子的特征荧光发射峰. 荧光实验表明在DMF溶液中Al3+会明显增强配体的荧光强度, 而对Eu3+的荧光强度影响却很小, 这使得1成为了优秀的比率式发光Al3+传感器. 在Al3+浓度处于0.02-0.1 mmol L—1范围内时, 配体与Eu3+荧光强度的比值与Al3+浓度成正比(斜率为18,502 mol—1 L). 本文证实了配体9位的羟基与Al3+之间的相互作用是引起配体荧光增强的主要原因.
