摘　　要：以3,5-二(吡啶-4-甲氧基)苯甲酸为多功能有机单体,1,3-间苯二甲酸为辅助配体,在水热条件下与过渡金属铬酸盐反应,得到金属-有机骨架材料化合物(1).化合物(1)具有二重互穿的三维(3,8)-连接网络结构,其拓扑符号为(42·6)2(44·622·82).室温下,化合物(1)在固态状态下和在常见有机溶剂中都表现出优良的荧光发射性能.此外,当向有机溶剂中加入硝基芳香族化合物之后,化合物(1)的荧光发生淬灭,因此,化合物(1)可作为高灵敏度的荧光传感器,用于硝基芳香族爆炸物的检测.A novel metal-organic framework compound(1)was synthesized by the reaction of 3,5-bis(pyridine-4-methoxy)benzoic acid with transition metal chromate under hydrothermal conditions and 1,3-isophthalic acid as an auxiliary ligand.Compound(1)has a three-dimensional interpenetrated(3,8)-connected network,and the topological symbol is(42·6)2(44·622·82).It is worth noting that compound(1)exhibits excellent fluorescence emission properties both in solid state and in common organic solvents at room temperature.In addition,when nitroaromatic compounds were added,the fluorescence of compound(1)in organic solvents was quenched.Therefore,compound(1)can be used as a highly sensitive fluorescence sensor for the detection of nitroaromatic explosives.
