Two novel pillared MOFs (metal organic frameworks) [Zn2(trz)2(tda)]·DMA CH3OH (1) and [Zn2(trz)2(bpdc)]·DMA (2) were obtained under solvothermal conditions. The resulting MOFs show similar structures but with different interlayer distances based on the different carboxylate ligands. 1 and 2 display a certain degree of framework stability in both acid/base solutions and water. The luminescence intensities of the activated phases 1a and 2a are sensitive to metal ions, particularly Fe(3+) and Cd(2+) ions. Furthermore, the luminescent properties of 1a and 2a well dispersed in different solvents have also been investigated systematically, which demonstrate distinct solvent-dependent luminescent spectra with emission intensities that are significantly quenched by acetone, nitrobenzene and trinitrotoluene.
在溶剂热条件下制备了两种新型柱撑金属有机框架材料(MOFs)[Zn2(trz)2(tda)]·DMA CH3OH(1)和[Zn2(trz)2(bpdc)]·DMA(2)。基于不同的羧酸配体,所得的MOFs具有相似的结构,但层间距不同。1和2在酸/碱溶液和水中均表现出一定程度的框架稳定性。活化相1a和2a的发光强度对金属离子敏感,尤其是Fe(3+)和Cd(2+)离子。此外,还系统研究了1a和2a在不同溶剂中良好分散时的发光性质,结果表明它们具有明显的溶剂依赖性发光光谱,其发射强度会被丙酮、硝基苯和三硝基甲苯显著淬灭。
