英文摘要	A bis-8-hydroxyquinoline "open chain crown ether" derivative (QP(3)Q) and its aluminum or zinc complex are synthesized. The steady state spectroscopy properties and fluorescence decay processes for the complexes (QP(3)Q-Zn2+ and QP(3)Q-Al3+) are studied. The composition and stability of the complexes are determined by their UV-Vis absorption. Both aluminum and zinc ions coordinated with QP(3)Q are in the proportion of 1:1 and the stability constant of QP(3)Q-Zn2+ and QP(3)Q-Al3+ are 620 and 1820 L (.) mol(-1), respectively. For QP(3)Q-Zn2+, the fluorescence emission peaks are at 436 nm with the quantum yield of 0.26 in methanol and 472 nm for the solid sample. The maximum wavelengths of the fluorescence of QP(3)Q-Al3+ are at 486 nm with quantum yield of 0.11 in methanol and 476 nm for its powder. The fluorescence of the complexes shows two exponential decay processes and the lifetimes for the main component are 44.8 and 11.3 ns for QP(3)Q-Zn2+ and QP(3)Q-Al3+, respectively.
