摘　　要：采用水热法成功合成了一个新的三元Ni(Ⅱ)基配位聚合物,{[Ni(L)(ndc)(H2O)2]}n(1)(L=4,4′-双(咪唑-1-基)-联苯,H2ndc=2,6-萘二甲酸).配合物1为二维4-连接的sql层,具有良好的热稳定性和水稳定性.荧光传感实验表明,1可以作为高选择性和高灵敏地检测有毒Hg(Ⅱ)离子的荧光探针.A new ternary Ni(Ⅱ)-based coordination polymer(CP), {[Ni(L)(ndc)(H2O)2]}n(1)(L=4,4′-bis(imidazol-1-yl)-biphenyl, H2ndc=2,6-naphthalenedicarboxylic acid), was successfully synthesized by hydrothermal methods. 1 is a two-dimensional 4-connected sql layer with highly thermal and water stability.Fluorescence sensing experiments shown that 1 can be utilized as a fluorescent probe for the highly selective and sensitive detection of toxic Hg(Ⅱ) ions.
