Abstract: The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 40.01 to 99.95% by weight of a luminescent organometallic complex X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of smaller than 0.2 eV [Δ(ES1(X))−(ET1(X)) ES1(Y)]. By doping, for example, an emitting layer containing a luminescent organometallic complex having a small S1−T1 splitting, with a fluorescent emitter the emission decay time can significantly be shortened without sacrificing external quantum efficiency (EQE) because of very efficient energy transfer.

Abstract: Disclosed are electroluminescent devices that comprise organic layers that contain certain organic compounds containing one ore more pyrimidine moieties. The organic compounds containing one ore more pyrimidine moieties are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.
