Three novel coordination polymers (CPs), namely, {[Ag(L)(MoO)·(CHCN)]} (1), {[Zn(L)(1,4-bdc)·2(1,4-Hbdc)]} (2), {[Cd(L)(1,4-bdc)]} (3) have been synthesized under solvothermal conditions by the reaction of bis(4-(4-1,2,4-triazol-4-yl)phenyl)methane (L) and varied metal salts. Their structures are determined by single X-ray crystal diffraction, and further characterized by elemental analysis, IR, TGA and PXRD. CP 1 with ammonium molybdate as a secondary ligand displays a 2D network with (2,3,3,3,4)-connected net topology and the point symbol of {4·8}{4·8·10}{8}, CP 2 and CP 3 with 1,4-Hbdc as a secondary ligand demonstrate 3D structures with different topologies. CP 2 exhibits high sensibility and low detection limit in the recognition of antibiotics (NZF, NFT and FZD) and pesticide (DCN) identification. CP 1 demonstrates good anti-tumor activity toward the tested glioma cells. The possible luminescent sensitivity and anti-tumor mechanisms are also discussed.
通过双（4-（4-1,2,4-三唑-4-基）苯基）甲烷（L）与不同金属盐在溶剂热条件下反应，合成了三种新型配位聚合物（CPs），即{[Ag(L)(MoO)·(CHCN)]} (1)、{[Zn(L)(1,4-bdc)·2(1,4-Hbdc)]} (2)、{[Cd(L)(1,4-bdc)]} (3)。通过单晶X射线晶体衍射确定了它们的结构，并通过元素分析、红外光谱、热重分析和粉末X射线衍射进一步表征。以钼酸铵作为第二配体的CP 1呈现出具有（2,3,3,3,4）连接网络拓扑结构和{4·8}{4·8·10}{8}点符号的二维网络，以1,4-Hbdc作为第二配体的CP 2和CP 3展示了具有不同拓扑结构的三维结构。CP 2在识别抗生素（NZF、NFT和FZD）和农药（DCN）方面表现出高灵敏度和低检测限。CP 1对测试的胶质瘤细胞表现出良好的抗肿瘤活性。还讨论了可能的发光敏感性和抗肿瘤机制。
