We have designed and successfully synthesized an alkylated aluminum quinoline derivative, tris(4-tridecyl-8-quinolinolato)aluminum (TDALQ), which could be used as an emitting material for solution-processible OLEDs. The synthesized material was identified by 1H NMR, IR and FAB-mass spectroscopy. To evaluate electroluminescent properties, TDALQ was spin-cast to fabricate thin film as an emitting layer on ITO/PEDOT substrate and LiF/Al double layer was used as electron injection electrode. The EL device showed a green light emission at 509 nm with CIE chromaticity coordinates of (0.31, 0.52). TDALQ made by a spin-coating method showed good film properties in AFM.
