Abstract

Transient electroluminescence (EL) measurements were made for a indium-tin-oxide (ITO)/ poly[(2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole)-p- phenylenevinylene] (PPPDPV)/ Al organic light-emitting diode (OLED), where PPPDPV is a derivative of poly(p-phenylenevinylene) (PPV) carrying the electron-transporting 2-(4-biphenyl)-5-(4-t-butylphenyl-1, 3,4-oxadiazole) moieties directly attached to the PPV backbone. As a result, we were able to explain the superior external quantum efficiency of a PPPDPV OLED device by a faster mobility as well as a longer EL lifetime in comparison to those for a PPV device.
