Abstract

To explain the origin of extremely high efficiencies of deep-blue fluorescent OLEDs with anisotropic-shaped anthracene derivatives, the enhancements of singlet-exciton generation efficiency and outcoupling efficiency were investigated by transient electroluminescence measurement and spectroscopic ellipsometry, respectively. This dual efficiency enhancement is important for understanding and further improving high-performance fluorescent OLEDs.
