A zinc-diphosphonate [Zn2(HEDP)(L)]·2H2O (1) was solvothermally prepared with L as a coligand (HEDP = 1-hydroxyethylidenediphosphonate, L = melamine). In 1, the {CPO3} tetrahedral units in HEDP ligand bridge the Zn2+ ions through corner sharing to form [-Zn2(HEDP)-]n neutral chains as subunits, which are further cross-linked by neutral L moieties into a novel three dimensional (3D) hybrid framework. The compound was characterized by infrared (IR) spectroscopy, elemental analyses (EA), powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and fluorescence spectroscopy. Notably, compound 1 displays blue photoluminescence with an emission maximum at about 354 nm.

杂二膦酸锌的合成,结构和荧光性质

以L作为大分子配体(HEDP = 1-羟基亚乙基二膦酸酯,L =三聚氰胺)溶剂热制备二膦酸锌[Zn 2(HEDP)(L)]·2H 2 O(1)。在图1中,HEDP配体中的{CPO 3 }四面体单元通过角共享桥接Zn 2+离子以形成[-Zn 2(HEDP)-] n中性链作为亚基,并通过中性L部分进一步交联成一个新颖的三维(3D)混合框架。通过红外光谱,元素分析(EA),粉末X射线衍射(PXRD),热重分析(TGA)和荧光光谱对化合物进行表征。值得注意的是,化合物1 显示出最大约354 nm的蓝色光致发光。
