Blue-emitting 2-methyl-9,10-di(2-napthyl)anthracene (MADN) and yellow-emitting 5,6,11,12-tetraphenylnaphthacene (rubrene) were used as cohost materials together with tris(8-hydroxyquinolinato)aluminum (Alq 3 ) to form emission layers doped with the red dopant molecule 4-(dicyanomethylene)-2-t-butyl-
