We report new phenanthroline‐based electron‐transport materials that greatly improve the operating lifetime of blue OLEDs relative to 4,7‐diphenyl‐1,10‐phenanthroline (Bphen). Use of these new materials results in efficient electron injection and transport, allowing for low voltage devices. Excellent performance is also observed for red and green OLEDs.
