Abstract

A rationally designed “bird-like” red fluorophore is employed to achieve an efficient solid-state photoluminescence quantum yield of 71.9% with strong intramolecular charge transfer and AIEE properties. The organic light-emitting diodes (OLEDs) fabricated using this superior thermal and photostable AIEE luminogen as a non-doped red emitter exhibited a maximum brightness of 23 931 cd m−2 with a low turn voltage of 4.6 V. Efficient optoelectronic performance is demonstrated through a single layer device architecture.
