Summary:The development of the ultrapure and highly efficient blue organic light‐emitting diodes is a very critical issue in the organic light‐emitting diodes. As an approach, boron‐nitrogen based multi‐resonance compounds have been developed. In this work, a new class of materials were designed and synthesized as the deep blue organic emitters for high efficiency organic light‐emitting diodes. Only carbon and nitrogen were used to design the materials to induce the multi‐resonance effect in the emitters. A deep blue color, a narrow emission spectrum and high efficiency by thermally activated delayed fluorescence were achieved using the new emitting materials.
