Abstract Red organic light-emitting diodes (OLEDs) utilizing a novel metal complex with a tridentate ligand, salicylidene-o-aminophenolato (8-quinolinoato) aluminium (Al(Saph-q)) as the host material, have been fabricated. In the OLEDs, N,N’-bis-(1-naphthyl)-N,N’-diphenyl-1,1’-biphenyl-4,4-’diamine (NPB) and 4-(dicyanomethylene)-2-(t-butyl)6-methyl-4H-pyran (DCJTB) are used as the hole-transporting and dopant materials, respectively. Compared with the OLEDs using tris(8-quinolinolato) aluminium (Alq3) as the host material, improved device performance with higher efficiency (0.62lm/W) has been achieved, in the consideration that developing host materials is a promising way to achieve excellent red emission OLEDs.
