通过水热法合成了一种具有三维孔状结构的金属有机框架物{[Cu(BPTC)0.5.(bpy)]. H2O}∞(BPTC=3,3′,4,4′‐苯甲酮‐四甲酸和 bpy =4,4′‐联吡啶).运用元素分析、红外光谱、X射线单晶衍射以及X射线粉末衍射等对其进行了结构表征,利用热重分析评价了其热稳定性.X射线单晶衍射分析表明标题配合物通过一维右手螺旋链联接成为二维层状结构,进而经由4,4′‐联吡啶联接成为三维孔状结构.当该孔状结构中包容的水分子被移除后,该金属有机框架物依然保持三维孔状结构.此外,实验还研究了标题配合物的磁学和固态荧光性质.

A 3D porous metal‐organic framework with formula as {[Cu(BPTC)0 5. ? (bpy)]?H2 O}∞ (BPTC = 3 ,3′,4 ,4′‐benzophenone‐tetracarboxylate and bpy = 4 ,4′‐bipyridine) has been successfully synthesized by hydrothermal process .The complex was characterized by sin‐gle‐crystal X‐ray diffraction ,IR spectroscopy ,X‐ray powder diffraction ,elemental analysis and thermogravimetric (TG ) analysis .Single‐crystal X‐ray diffraction confirms that right‐handed helical chains exist in the 2D layers ,which are further formed into 3D porous network via bpy linkers ,and the 3D framework remains intact after the guest water molecules encapsu‐lated in the cavities are removed .Magnetic property study of the complex proves that it pres‐ents antiferromagnetic coupling through the (O2 C-C-C-CO2 )2 bridges .The ligand‐to‐met‐al‐charge‐transfer (LMCT ) transitions exist in the solid‐state photoluminescence .
