摘　　要：采用亚组分自组装方法,构建了基于Ir(Ⅲ)有机金属模块的异核多金属Zn_(3)Ir_(2)构型配位超分子笼.通过核磁共振氢谱、质谱以及X射线单晶衍射对Zn_(3)Ir_(2)的分子结构进行了表征.Ir-Ir距离约为1.17nm,Zn-Zn距离约为0.78nm.Zn_(3)Ir_(2)分子笼结构中有一个较大且略微扭曲的矩形窗口,尺寸为0.79nm×0.75nm.所获得的Zn_(3)Ir_(2)分子笼具有优异的磷光发射能力和限域空腔微环境,在分子识别、光催化和药物递送等领域具有良好的应用前景.Based on Ir(Ⅲ)organometallic module,a coordination supramolecular cage with heteronuclear multi-metal Zn _(3)Ir_(2) configuration is constructed using subcomponent self-assembly approach.The molecular structure of Zn _(3)Ir_(2) is characterized by 1H NMR,mass spectrometry and single-crystal X-ray diffraction.The Ir-Ir distance is approximately 1.17 nm,while the Zn-Zn distance is around 0.78 nm.The structure of Zn _(3)Ir_(2) molecular cages features a large,slightly twisted rectangular window with dimensions of 0.79 nm×0.75 nm.The obtained Zn _(3)Ir_(2) molecular cages have excellent phosphorescence emission property and confined cavity microenvironment,making them highly promising for applications in molecular recognition,photocatalysis and drug delivery.
