The present invention relates to compounds which are suitable for use in electronic devices, and to electronic devices, in particular organic electroluminescent devices, comprising these compounds. The compounds have a a dibenzofuran, dibenzothiophene or a fluorene group substituted in the 1-position, either directly or through a linking group, to a carbon atom of a heteroaromatic group with one or two nitrogen atoms in a bicyclic 6/6 core, or to a carbon or nitrogen atom of a heteroaromatic group with two nitrogen atoms in a bicyclic 5/6 core and is further substituted with a group selected from dibenzofuran, dibenzothiophene, fluorene or carbazole.
본 발명은, 특히 유기 전계발광 소자에서 삼중항 매트릭스 재료로서 사용하기 위한, 전자-결핍 헤테로아릴 기에 의해 치환되어 있는 카르바졸, 디벤조푸란, 디벤조티오펜 및 플루오렌 유도체를 기재한다. 본 발명은 또한 본 발명에 따른 화합물의 제조 방법 및 이러한 화합물을 포함하는 전자 소자에 관한 것이다.
The present invention describes amines with dibenzofuran or dibenzothiophene groups in combination with carbazole, especially for use as triplet matrix materials in organic electroluminescent devices. The invention further relates to a process for preparing the compounds of the invention and to electronic devices comprising these compounds.
The present invention concerns particular fluorenes, the use of the compound in an electronic device, and an electronic device containing at least one of these compounds. The present invention further concerns a method for producing the compound and a formulation and composition containing one or more of the compounds.
