The present invention relates to heteroleptic complexes comprising a phenylimidazole or phenyltriazole unit bonded via a carbene bond to a central metal atom, and phenylimidazole ligands attached via a nitrogen-metal bond to the central atom, to OLEDs which comprise such heteroleptic complexes, to light-emitting layers comprising at least one such heteroleptic complex, to a device selected from the group consisting of illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED, to the use of such a heteroleptic complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge blocker.

Heteroleptic carbene complexes and the use thereof in organic electronics

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 2 to 40% by weight of a triplet emitter X having a difference of the singlet energy (E(X)) and the triplet energy (E(X)) of less than or equal to 0.4 eV [Δ(E(X)) −(E(X))≤0.4 eV], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the triplet emitter X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the triplet emitter X(E(X)) is greater than the singlet energy of the fluorescent emitter Y(E(Y)) [(E(X))>E(Y)]. By doping, for example, an emitting layer containing a luminescent organometallic complex having a small S-Tsplitting, with a fluorescent emitter the emission decay time can significantly be shortened without sacrificing external quantum efficiency (EQE) because of very efficient energy transfer.

Highly efficient OLED devices with very short decay times

The present invention relates to the use of transition metal-carbene complexes in organic light-emitting diodes (OLEDs), to a light-emitting layer, to a blocking layer for electrons or excitons, or to a blocking layer for holes, each comprising these transition metal-carbene complexes, to OLEDs comprising these transition metal-carbene complexes, to devices which comprise an inventive OLED, and to transition metal-carbene complexes.

Metal complexes comprising diazabenzmidazolocarbene ligands and the use thereof in OLEDS

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 2 to 40% by weight of a triplet emitter X having a difference of the singlet energy (E(X)) and the triplet energy (E(X)) of less than or equal to 0.4 eV [&#x394;(E(X))&#x2212;(E(X))&#x2264;0.4 eV], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the triplet emitter X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the triplet emitter X (E(X)) is greater than the singlet energy of the fluorescent emitter Y (E(Y)) [(E(X))&#x3e;E(Y)]. By doping, for example, an emitting layer containing a luminescent organometallic complex having a small S-Tsplitting, with a fluorescent emitter the emission decay time can significantly be shortened without sacrificing external quantum efficiency (EQE) because of very efficient energy transfer.
