摘要
[Objectives]The paper was to explore a new method for preparing nano ZnO particles.[Methods]A mixture of 2,6-di(2′,4′-dicarboxylphenyl)pyridine(0.05 mM),Zn(NO_(3))2·6H_(2)O(0.1 mM)were added to the solution of DMA(3 mL)and H_(2)O(3 mL),and heated at 90℃for 12 h.The PXRD,TGA and fluorescence properties were characterized.[Results]Transparent block crystals of the[Zn_(2)(2,6-ddpp)(DMA)_(3)(H_(2)O)·H_(2)O]n were obtained(yield 85.4%,based on Zn).The Zn-MOF framework would collapse to form ZnO particles when the temperature exceeded 350℃.[Conclusions]A new Zn(II)-MOF is successfully constructed,and the compound exhibits monoclinic P21/c space group.The results will provide a theoretical basis for the preparation of nano ZnO.
