Electroluminescent (EL) properties of 6,6 ' ' ' ' -dimethyl-4 ' ,4 ' ' ' ' -diphenyl-2,2 ' :6 ' ,2 " :6 " ,2 ' ' ' :6 ' ' ' ,2 ' ' ' ' -quinquepyridine (DMDPQPY) have been examined. The EL results of typical single layer devices indicate that emitting layer thickness can influence the emission wavelength. The introduction of a hole transporting layer in the double layer device enhances the luminance greatly, showing a better charge balance. It is proposed that 2,6-linked poly(oligo) pyridine derivatives are promising to form a new class of EL material both as emitter and as carrier transporter.
