摘要

Provided are a composition and an organic light-emitting device including the same, wherein the composition includes a platinum-containing organometallic compound, a first compound, a second compound, and a third compound.

說明書

  • ring CY711 and ring CY721 may each be the same as described in connection with CY71 and CY72, respectively,
  • Z71 to Z76 may each be the same as described in connection with R1,
  • Z73 and/or Z75 may optionally be linked to neighboring ring CY711 and/or ring CY712, respectively, to form a C5-C30 carbocyclic group or a C1-C30 heterocyclic group, and
  • * indicates a binding site to a neighboring atom.
    Third Compound (WBG Host)

    • The third compound may have a greater band gap than a band gap of the first compound and a band gap of the second compound.

    For example, a gap between a HOMO energy level of the third compound and a LUMO energy level of the third compound may be equal to or greater than about 4.1 eV, for example, equal to or greater than about 4.3 eV.

    In an embodiment, the third compound may include at least one group represented by Formula 4A, 4B, or 4C:
