## Abstract **Summary:** 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 __Ξ·__~ext~ = 10.4% at __J__ = 0.11 mA · cm^βˆ’2^ for the macrocycl
