A highly efficient simplified organic light‐emitting diode (OLED) with a molecularly controlled strategy to form near‐perfect interfacial layer on top of the anode is demonstrated. A self‐organized polymeric hole injection layer (HIL) is exploited increasing hole injection, electron blocking, and reducing exciton quenching near the electrode or conducting polymers; this HIL allows simplified OLED comprised a single small‐molecule fluorescent layer to exhibits a high current efficiency (∼20 cd/A).
