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. self-organized polymeric hole injection (HIL) exploited increasing injection, electron blocking, and reducing exciton quenching near electrode or conducting polymers; this HIL allows OLED comprised single small-molecule fluorescent exhibits high current efficiency (∼20 cd/A).
