摘要:
The present invention describes novel organometallic compounds which are phosphorescent emitters. Such compounds can be used as active components (=functional materials) in a variety of different applications which can in the widest sense be considered part of the electronics industry. The compounds of the invention are described by the formulae (I), (Ia), (II) and (IIa).
摘要:
The present invention relates to a process for preparing highly pure tris-ortho-metallated organoiridium compounds and such pure organometallic compounds which may find use as coloring components in the near future as functional components (=functional materials) in a series of different types of applications which can be classed within the electronics industry in the widest sense.

摘要:
The present invention relates to the improvement of organic electroluminescent devices, which is characterized in that the emitting layer (EML) consists of a mixture of two substances, one having hole-conducting properties and the other having light-emitting properties, and at least one of these compounds containing a spiro-9,9′-bifluorene unit.
摘要:
The present invention relates to electronic devices comprising organic semiconductors whose content of halogens is less than 20 ppm. This increases the lifetime and the efficiency of the corresponding electronic devices, and these materials are thus better suited to use in organic electronic devices than materials with a higher halogen content. The present invention further relates to corresponding organic semiconductors and to a process for their production.
