Abstract

Abstract Eight 5, 7-diaryl-8-hydroxyquinoline ligands were synthesized and characterized by 1 H, 13 C 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.
