Synthesis of Novel Zn Metal Complexes Based on 8-Hydroxyquinoline with Trifluorobenzene Group and Their Photophysics Contrastive Study
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.
