| 摘要: 利用异构的半刚性多羧酸配体3，5-二（3-羧基苯氧基）苯甲酸（3-H3BCP），3，5-二（4-羧基苯氧基）苯甲酸（4-H3BCP）和刚性双三唑配体4-（4-（4H-1，2，4-三唑-4-基）苯基）-4H-1，2，4-三唑（L）在相似的水热条件下与金属Zn（Ⅱ）离子反应，制得混合配体的配位聚合物{[Zn（3-HBCP）（L）]·0.5H2O}n（1）和[Zn（4-HBCP）（L）0.5]n（2）。配合物1为含有双核簇的（4，4）连接的二维网络结构，而配合物2为三重互穿的2D+2D→2D平行网络结构。通过X射线单晶衍射、元素分析、红外光谱、紫外光谱以及荧光光谱其进行了表征。 |

| Abstract: Two isomeric semi-rigid multi-carboxylate ligands 3,5-bi(3-carboxyphenoxy) benzoic acid (3-H3BCP), 3,5-bi(4-carboxyphenoxy)benzoic acid (4-H3BCP) and one rigid bridging bis-triazole 4-(4-(4H-1,2,4-triazol-4-yl)phenyl)-4H-1,2,4-triazole (L) have been employed to react with Zn(Ⅱ) salts under similar solvothermal reactions. Two novel zinc(Ⅱ) mixed-ligand coordination polymers, namely, {[Zn(3-HBCP)(L)]·0.5H2O}n (1) and[Zn(4-HBCP)(L)0.5]n (2) have been isolated. Complex 1 displays a (4,4)-connected 2D cluster-based network while 2 displays an usual 3D fold 2D+2D→2D parallel entangled network. Solid-state luminescent properties and thermal analyses of 1~2 also have been determined indicating strong fluorescent emissions and good thermal stabilities. Different coordination modes of two semi-rigid multi-carboxylate ligands and L also have been briefly discussed, which also reveal great potential in the construction of these novel mixed-ligand luminescent frameworks with diverse structural motifs and unique functional properties. |
