Fluorescent red organic light-emitting devices (OLEDs) with narrow emission and negligible current-induced quenching by using a pentacene derivative of 6,13-di-(3,5-diphenyl)phenylpentacene (PDT) doped emitting system were demonstrated. With the incorporation of C60 outcoupling layer, the PDT-based top-emitting OLED showed superior electroluminescence performances with Commission Internationale d’Eclairage color coordinates of (0.64, 0.36) and luminous efficiency of ∼3 cd/A. To clarify the actual energy transfer process in PDT-doped emitting system, the Förster’s radius was calculated. The results indicated that the energy transfer process is predominantly from the host of tris(8-hydroquinoline) aluminum to guest of PDT via the assistant dopant of 5,6,11,12-tetraphenylnaphthacene.
