Abstract
The Schiff-base ligand aluminum complex, [AlLMe2] [L = ortho-C6H4(NC6H3Me2-2,6)(CH=NC6H3Me2-2,6)], has been synthesised and characterised; its electroluminescent properties are reported. Electroluminescent devices were fabricated by doping [AlLMe2] in a polymer host of poly (vinylcarbazole) (PVK) and 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazole (PBD) using a simple solution spin-coating technique. The single-layer polymer organic light-emitter devices exhibited green emission, showed maximum current efficiency of 1.4 cd/A and maximum luminance of near 1000 cd/m2.
