Abstract

Two types of bis(2,5-diphenyl-1,3,4-oxadiazole)s, macrocyclic and acyclic, were prepared and evaluated as electron-transporting and hole-blocking materials in phosphorescent EL devices. Maximum efficiencies of η_ext= 10.4% at J=0.11 m A ·cm^-2 for the macrocycle and η_ext = 14.1% at J=3.01 mA ·cm^-2 for the acycle were observed. X-ray crystallographic analysis and DSC measurements revealed a strong intermolecular interaction between the macrocycles and weaker intermolecular interactions between the acycles. The EL characteristics depend on the intermolecular interactions.
