摘要:

采用分子构筑块策略设计合成了一个含萘基的直线型有机羧酸配体4,4′-(9,10-naphthalenediyl)bis-benzoic acid(H2NDBA), 以构筑特定的骨架结构. 利用调节剂法, 通过八水合氯氧化锆与有机配体H2NDBA的溶剂热反应, 合成了具有预期fcu拓扑结构的[Zr6(μ3-O)4(μ3-OH)4(NDBA)6]·7DMF·4H2O(JLU?MOF100). 该MOF材料具有高孔隙率和良好的水稳定性. 得益于有机配体中的萘基团, JLU?MOF100具有优异的荧光性质, 基于荧光猝灭效应, 在水中对硝基芳烃爆炸物展现出良好的荧光检测性能.

Abstract:

Guided by molecular building block(MBB) approach, a naphthalene-based linear organic ligand 4,4′-(9,10-naphthalenediyl)bis-benzoic acid(H2NDBA) is designed and synthesized to build the oriented framework. By using the modulator method, the solvothermal reaction of ZrOCl2·8H2O and H2NDBA ligand yields the [Zr6μ3-O)4·(μ3-OH)4(NDBA)6]·7DMF·4H2O(JLU?MOF100) with anticipated fcu topology. JLU?MOF100 displays high porosity and good water stability. Benefiting from the naphthalene group in the ligand, JLU?MOF100 exhibits significant fluorescent properties. It shows good performance in the detection of different nitroaromatic explosives in water by quenching effect.

Key words: Zirconium metal-organic framework, Naphthalene group, Fluorescent detection, Nitroaromatic explosive
