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.
