Abstract

Both photoluminescence (PL) and electroluminescence (EL) properties of 6,6‴′-dimethyl-4′, 4‴-diphenyl-2,2′:6′,2″:6″,2‴:6‴, 2‴′-quinquepyridine (DMDPQPY), a 2,6-linked oligopyridine derivative, have been investigated. Two maxima are observed from its PL spectra in solid state, but only one peak appears in its PL in solutions. Emission from the single layer device with indium-tin-oxide (ITO) and Al as the respective anode and cathode (ITO/DMDPQPY/Al) is very weak, but introduction of a hole transporting layer polyvinylcarbazole (PVK), in the double layer device (ITO/PVK/DMDPQPY/Al), increases the luminance significantly indicating a better charge balance. Two peaks appear in the EL spectra, one at 419 nm and another at 536 nm, ascribed to PVK and DMDPQPY respectively.
