合成了两种基于四齿原位配体CuI 3（L1）2（L2）[PMoVI 8VV 4 O 40（VIVO）2]·2 H2O（1）和[CuI 2Cl 2（L3）]（2）的新型金属有机骨架（MOFs）（L1 = 1，4-双（咪唑-1-基甲基）苯，L2 = 1，2，4，5-四（4-吡啶基）-苯L3 = a-1-羟基-e，e，e，e-1，2，4，5-四通过水热法合成了4-（4-吡啶基）环己烷，并通过元素分析、红外光谱、热重分析和单晶X射线衍射对其进行了表征，分别在此，化合物1代表了在基于POM的MOFs中采用双齿偶联产生新型四齿共面染料分子的第一个实例。由于节点的定义不同，它还展示了具有两种拓扑结构（4284）（4283101）（86）2和（4383）（4284）（446289）（4106183）的独特3D MOF。化合物2显示了基于CuI离子和原位合成的配体L3的双重对角/对角倾斜互穿。有趣的是，反应条件在来自相同前体bpp（bpp = 1，3-双（4-吡啶基）丙烷）的原位配体（L2和L3）的支配中起重要作用。此外，还详细研究了化合物1的电化学和电化学性质。
Two novel metal–organic frameworks (MOFs) based on different tetradentate in situ ligands, CuI3(L1)2(L2)[PMoVI8VV4O40(VIVO)2]·2H2O (1) and [CuI2Cl2(L3)] (2) (L1 = 1,4-bis(imidazol-1-ylmethyl)benzene, L2 = 1,2,4,5-tetra(4-pyridyl)-benzene L3 = a-1-hydroxy-e,e,e,e-1,2,4,5-tetra(4-pyridyl)cyclohexane) have been rationally hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, TG analyses, and single-crystal X-ray diffraction, respectively. Here, compound 1 represents the first example that dehydrogenative coupling has been employed to yield a novel tetradentate coplanar dye molecule in POM-based MOFs. It also exhibits unique 3D MOFs with two topologies (4284)(4283101)(86)2 and (4383)(4284)(446289)(4106183) due to different definitions of nodes. Compound 2 shows a two-fold diagonal/diagonal inclined interpenetration based on CuI ions and in situ synthesized ligands L3. Interestingly, reaction conditions play important roles in the domination of in situ ligands (L2 and L3) from the same precursor bpp (bpp = 1,3-bis(4-pyridyl)propane). Additionally, electrochemical and photocatalysis properties of compound 1 have also been minutely investigated.
