56.1: <i>Invited Paper</i> : Excited State Interactions in P‐OLEDs: Implications For Efficiency And Lifetime

Abstract

Abstract A fluorescent blue P‐OLED has high densities of triplet excited states within the emissive layer. In this paper we will present an efficiency and degradation analysis of model P‐OLED devices and materials, and demonstrate that control of triplet transfer and annihilation processes are of crucial importance in realising the efficiencies and device stabilities required for commercialisation of the technology.
