摘要

采用元素分析、红外光谱、粉末x射线衍射(PXRD)、热重分析(TGA)和单晶x射线衍射对三羧酸配体(H3L =联苯-2,4′，5-三羧酸)[Cd3(L)2(H2O)4](1)的金属有机骨架(MOF)进行了表征。荧光研究表明，1对水溶液中丙酮和Fe3+离子具有较高的猝灭效率。因此，它可以作为一种新型的荧光探针来检测水中的溶剂分子和金属离子。

Crystal structure and fluorescence-based sensor properties of a Metal-Organic Framework

A Metal-Organic Framework (MOF) based on a tricarboxylic acid ligand (H3L = biphenyl-2,4′,5-tricarboxylic acid), namely [Cd3(L)2(H2O)4] (1), had been prepared and characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD), thermogravimetric analyses (TGA), and single-crystal X-ray diffraction. Fluorescence studies showed that 1 has high quenching efficiency for testing acetone and Fe3+ ions in aqueous systems. Therefore, it can be used as a new type of fluorescence probe to detect solvent molecules and metal ions in water.
