介绍了三种新型含四唑基配体锌配位聚合物的合成及其发光性能。在水热（溶剂热）反应条件下，以Zn(ClO(4))(2)为Lewis酸，乙腈或对甲苯腈与叠氮化钠进行原位[2+3]环加成反应（Demko-Sharpless四唑合成法），分别得到[Zn(CH(3)CN(4))(2)](3)(H(2)O)(1)和[Zn(4- mptz)(2)](3) [4- mptz = 5-（4-甲基苯基）四唑]。另一方面，四唑与Zn(OAc)(2)在水热条件下直接反应得到[Zn(HCN(4))(2)](2)。图1的结构显示了一个以金刚石亚单元作为连接节点的超级类金刚石拓扑网络。对于2，也发现了类金刚石拓扑网络，但它是2倍互穿的。图3的结构揭示了一个二维的六边形网状层状网络，网络中的相邻层按ABAB顺序堆叠。光致发光研究表明，在室温下，配位聚合物1、2和3分别在λ (max) = 396、418和397 nm处表现出强烈的蓝色荧光发射。
The syntheses and luminescent properties of three novel zinc coordination polymers containing tetrazolyl ligands are described. In situ [2+3] cycloaddition reactions of acetonitrile or p-tolylnitrile with sodium azide in the presence of Zn(ClO(4))(2) as a Lewis acid (Demko-Sharpless tetrazole synthesis method) under hydrothermal (solvothermal) reaction conditions gave [Zn(CH(3)CN(4))(2)](3)(H(2)O) (1) and [Zn(4-MPTZ)(2)] (3) [4-MPTZ = 5-(4-methylphenyl)tetrazole], respectively. On the other hand, [Zn(HCN(4))(2)] (2) was obtained by directly reacting tetrazole with Zn(OAc)(2) under hydrothermal reaction conditions. The structure of 1 shows a super-diamond-like topological network with a diamond subunit as a connecting node. For 2, a diamond-like topological network is also found, but it is 2-fold interpenetrated. The structure of 3 reveals a 2D layered network with a hexagonal net, with the adjacent layers in the network stacked in an ABAB sequence. Photoluminescence studies revealed coordination polymers 1, 2, and 3 exhibit strong blue fluorescent emissions at lambda(max) = 396, 418, and 397 nm, respectively, in the solid state at room temperature.
