Three 8-hydroxyquinoline derivatives (E)-2-[2-(2-nitrophenyl)vinyl]-8-hydroxyquinoline (4a), (E)-2-[2-(3-nitrophenyl) vinyl]-8-hydroxyquinoline (4b), (E)-2-[2-(4-nitrophenyl)vinyl]-8-hydroxyquinoline (4c) and their zinc complexes 5a~5c have been synthesized and identified by 1H NMR, FFIR, MS techniques and elemental analyses. The aggregation behavior of Zn(OAc)2 and the ligands 4a~4c in solution was investigated by UV-vis. The luminescence properties of compounds 5a~5c were investigated by fluorescence spectra in solid and DMF solution at room temperature. The results showed that the λmax of compounds 5a~5c were 596, 625 and 592 nm in solid, and were 562, 536 and 618 nm in DMF solution. The comparative study of the luminescent properties of 5a~5c showed that the emission λmax can be tuned by introducing nitro groups at different positions of benzene.
