The complex has been characterized by elemental analysis,FT-IR,TG,PXRD and X-ray single-crystal structure analysis and the fluorescence property has also been studied. As a result,complex 1 possesses a two-dimensional（2-D） structure through DPA ligands interconnecting Cd2＋ ions. Complex 1 emits the intense fluorescence of 420 nm in the solid state at room temperature.展开更多
