| Abstract: |
| Two 8-hydroxyquinoline derivatives of（E）-2-［2-（2,4,6-trifluorophenyl）vinyl］-8-hydroxylquinoline（B）,（E）-5-［2-（2,4,6-trifluorophenyl） imino］-8-hydroxyquinoline（C） and their zinc complexes D and E were designed and synthesized,and identified by NMR，IR，MS spectra and elemental analysis.The aggregation behaviors of Zn（AcO）2 and the ligands B and C were investigated by UV-vis spectrum in methyl solution.The luminescence properties of the compounds B and C were investigated by fluorescence spectra in methol solution at room temperature.The results showed that the fluorenscence peaks of compounds D and E were 599 nm and 572 nm，respectively.Their fluorescence properties showed that the luminescence wavelengths of 5-substitued-8-hydroxyquinoline derivatives and 2-substitued-8-hydroxyquinoline derivatives shift to red compared with that of 8-hydroxyquinoline.Meanwhile，the results for determination of solid fluorescence lifetime showed that the complex of D had a long fluorescence lifetime. |
