Three new complexes BPh2(mqp) (1), Al(CH3)(mqp)(2) (2), and AZ(mqp)(3) (3) have been;: synthesized and characterized, where mqp = 2-(4'-methylquinolinyl)-2-phenolato. The mqp ligand in compounds 1 and 2 act as a chelate ligand, while in compound 3 it acts as both a chelate ligand and a terminal ligand. The boron center in 1 has tetrahedral geometry, while the aluminum ion in 2 and 3 has trigonal-bipyramidal geometry. In CH2Cl2 solution, these compounds emit a green, a green-blue, and a whitish blue color (lambda = 514, 515; 497 nm), respectively, when irradiated by UV light. In the solid state, these three compounds emit. green, a blue, and a whitish blue color, respectively (lambda = 520, 474, 500 nm). Electroluminescent devices using compound 3 as an emitter have been fabricated.
