A stable glassy structure enhances the lifespan and performance of molecular blue‐light‐emitting devices: The authors present an easily synthesized tetraphenylsilane framework derivatized with one or more triphenylamino‐oxadiazole groups (see Figure), for which DSC showed no measurable crystallization tendency. Trilayer OLED devices containing this chromophore exhibit bright blue electroluminescence exceeding 20000 cd/m 2 .
