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.
本发明涉及适用于电子设备的化合物,以及包括这些化合物的电子设备,特别是有机电致发光器件。这些化合物在1-位通过直接或通过连接基团与具有一个或两个氮原子的双环6/6核心的杂芳族基团的碳原子,或者与具有两个氮原子的双环5/6核心的杂芳族基团的碳或氮原子上发生取代,进一步取代为从二苯并呋喃、二苯并噻吩、芴或咔唑中选择的基团。
