The present invention describes electronic devices and compositions that can be used in electronic devices, the electronic devices including a sensitizer and a fluorescent emitter, wherein the sensitizer is a phosphorescent compound and wherein at least one of the two following conditions (I) or (II) must be satisfied, it being preferable when condition (I) is satisfied:(FE)−()≥  (I)(FE)−()≤  (II)wherein, e.g., X, Y are each −0.5 eV; S(FE) is the energy of the first excited singlet state of the fluorescent emitter; S(S) is the energy of the first excited state of the sensitizer; S(FE) is the energy of the first excited singlet state of the fluorescent emitter; S(S) is the energy of the first excited state of the sensitizer; and wherein the photoluminescence spectra of the sensitizer and of the fluorescent emitter are determined at room temperature.

Electroluminescent devices having sensitizer and fluorescent emitter

The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.

Materials for organic electroluminescent devices

The present application relates to an amine compound according to formula (I), (II) or (III) which is suitable for use in electronic devices.

Compounds for electronic devices

A composition containing at least one sensitizer and at least one fluorescent emitter, wherein the sensitizer is a phosphorescent compound and wherein the fluorescent emitter is a sterically shielded compound having a shielding factor (SF) of not less than 0.45. In addition, the invention is to a fluorescent electronic device containing a sensitizer and a fluorescent emitter, wherein the sensitizer is a phosphorescent compound and wherein the fluorescent emitter is a sterically shielded compound.

Composition and an electronic device containing a sensitizer and a fluorescent emitter

The present invention relates to an organic electroluminescent device comprising a hole-injection layer comprising a metal complex as a main component and a method for producing the organic electroluminescent device.
