dc.description.abstract Quinoline-derived fluorescent complexes were designed en

dc.description.abstract and characterized. The H-1 NMR spectra of complexes 1 and 5, containing A13+, were consistent with an octahedral structure having approximate D-3 symmetry, and the results supported the favored facial isomer (fac). Data for complexes 2-4 and 6-8 supported the formation of tetrahedral structures. Intense luminescence was detected for complexes 5-8, even with the naked eye, as indicated by quantum yield values of 0.087, 0.094, 0.051, and 0.021, respectively. Furthermore, in contrast to 5-nitro-8-hydroxyquinoline, the 5-chloro-8-hydroxyquinoline ligand exhibited bands at different energies depending on the coordinated, metal, which supported its potential application in ionic and biological probes, as well as in cell imaging.
