An amorphous photoluminescent material based on a dithienylbenzothiadiazole structure has been used for the fabrication of organic red‐light‐emitting diodes. The synergistic effects of the electron‐transport ability and exciton confinement of the emitting material allow for the fabrication of efficient pure‐red‐light‐emitting devices without a hole blocker.
