摘　　要：在水热条件下,利用多齿的单-和双-三唑衍生物,制备了3种基于多金属氧簇基(POM)的Cu(Ⅱ)和Cu(Ⅰ)杂化材料,即{[Cu(L1)2(Mo4O13)]·2H_2O}n(1),{[Cu1.5(L2)(HL2)(H_2O)(Mo4O13)]·2H2O}n(2),{[Cu2(L3)1.5(Mo4O13)]·H_2O}n(3)(L1=4-pyridine-2-1,2,4-triazole,HL2=3-(4H-1,2,4-triazol-4-yl)benzoic acid,L3=trans-4,4′-azo-1,2,4-triazole)。通过单晶X射线衍射、傅里叶变换红外光谱和粉末X射线衍射分析确定了它们的结构。在1中,Mo4O132-阴离子和Cu(Ⅱ)中心通过双齿L1相互连接,最终形成了二维(2D)POMs基的Cu(Ⅱ)杂化金属-有机骨架。在2中,Mo4O132-阴离子和Cu(Ⅱ)中心通过桥接水原子(O18),双齿HL2和三齿L2-相互连接,最终形成了三维(3D)POMs基的Cu(Ⅱ)微孔金属-有机骨架。在3中,L3配体桥接相邻的Cu(Ⅰ)中心和Mo4O132-阴离子,最终形成独特的双重穿插结构的3DPOMs基的Cu(Ⅰ)杂化配位框架。光催化实验研究表明,样品1～3对于不同有机染料罗丹明B (RhB)、亚甲基蓝(MB)和甲基橙(MO)都具有很好的光催化降解能力。Three novel polyoxometalate （POM）-based Cu（Ⅱ） and Cu（Ⅰ） hybrid materials with multi-dentate mono-and bis-triazole derivatives, namely {[Cu（L1）2（Mo4O13）]·2H2O}n （1）, {[Cu1.5（L2）（HL2）（H2O）（Mo4O13）]·2H2O}n （2）, {[Cu2（L3）1.5（Mo4O13）]·H2O}n （3） （L1=4-pyridine-2-1,2,4-triazole, HL2=3-（4H-1,2,4-triazol-4-yl） benzoic acid,L3=trans-4,4＇-azo-1,2,4-triazole） have been designed and synthesized by hydrothermal method. The structures of 1-3 have been determined by single crystal X-ray diffraction, FT-IR infrared spectra and powder X-ray diffraction analyses. In 1, Mo4O132- anions and Cu（Ⅱ） centers are inter-linked by bidentate L1, which are arranged into 2D POMs-based Cu（Ⅱ） hybrid metal-organic framework. In 2, Mo4O132- anions and Cu（Ⅱ） centers are inter-linked via bridging aqua atoms （O18）, bi-dentate HL2 and tri-dentate L2-, which are arranged into 3D POM-based Cu（Ⅱ） micro-porous metal-organic framework. In 3, L3 ligands bridge neighboring Cu（Ⅰ） centers and Mo4O132- anions, which ultimately forms unique two-fold interpenetrating 3D POM-based Cu（Ⅰ） hybrid coordination framework. Photocatalytic activities for decomposition of different organic dyes of rhodamine B （RhB）, methylene blue （MB） and methyl orange （MO） have been investigated for 1-3, indicating that 1-3 are good candidates for photocatalytic degradation of the organic dyes.
