Eight 5,7-diaryl-8-hydroxyquinoline ligands were synthesized and characterized by H-1, C-13 NMR spectroscopy and mass spectrometry. The electron-donating and electron-withdrawing aryl groups were attached to the 5- and 7-positions of the quinolinolate ring via Suzuki coupling reaction. The aluminum complexes of these ligands exhibited successful tuning in the emission color, covering a large segment of the visible spectrum. (C) 2013 Elsevier Ltd. All rights reserved.
