Exciplex‐Forming Cohost Systems with 2,3‐Dicyanopyrazinophenanthrene‐based Acceptors to Achieve Efficient Near Infrared OLEDs

Two new 2,3‐dicyanopyrazinophenanthrene‐based acceptors (A) p‐QCN and m‐QCN were synthesized to blend with a donor (D) CPTBF for the exciplex formation. The energy levels of p‐QCN and m‐QCN are modulated by the peripheral substituents 4‐ and 3‐benzonitrile, respectively. Exciplex‐forming blends were...
