基于半刚性四面体四齿配体构筑的Zn(Ⅱ)/Cd(Ⅱ)配位聚合物及其性质（英文）

Crystal Structures and Properties of Zn(Ⅱ)/Cd(Ⅱ) Coordination Polymers Based on Semirigid Tetrahedral Quadridentate Ligand

在水热的条件下,利用四(4-吡啶氧甲基)甲烷(L1)或四(3-吡啶氧甲基)甲烷(L2)、1,4-萘二甲酸(1,4-NDC)和d10金属离子发生自组装反应合成了2个化合物{[Cd2(L1)(1,4-NDC)2]·2H2O}n(1)和{[Zn2(L2)(1,4-NDC)2]·DMF·3H2O)}n(2)。单晶结构表明化合物1是通过L1配体与一维链[Cd(1,4-NDC)]n相连构建而成的三维骨架化合物,而化合物2是一对螺旋链与另外的一维链相互垂直交联而形成二维网络结构。更为重要的是,通过引入2种不同空间位阻的配体,研究了辅助配体对金属有机配位聚合物结构多样性的影响。另外,它们的荧光性质也做了相应的探讨。

Two complexes, {[Cd2（L1）（1,4-NDC）2]·2H2O}n（1）, （1） and {[Zn2（L2）（1,4-NDC）2]·DMF·3H2O）}n（2）（Ll=tetrakis（4-pyridyloxymethylene）methane, k=tetrakis（3-pyridyloxymethylene）methane, 1,4-NDC=naphthalene-l,4-dicarbox-ylic acid） are obtained by the self-assembly reaction of L1 or L2, 1,4-NDC, and dl metal ions under solvothermalconditions. The X-ray analysis reveals that 1 is constructed from a 1D zigzag chain [Cd（1,4-NDC）], which islinked by L1 ligand to yield a 3D framework. And yet in case of 2, one double helix is mutually interdigitated byanother 1D chain into a 2D network. Above all, the effect of steric hindrance of the auxiliary linker on thestructural diversity of CPs can be discussed in great detail by the introduction of two kinds of auxiliary linkerswith different steric hindrance. Additionally, their luminescent properties are also observed. CCDC： 1019510, 1;1019511, 2.
