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 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,以及包含这些化合物的电子设备,特别是有机电致发光设备。这些化合物中的二苯并呋喃、二苯并噻吩或芴基团在 1 位上直接或通过连接基团与双环 6/6 核心中带有一个或两个氮原子的杂芳香族基团的碳原子取代,或与双环 5/6 核心中带有两个氮原子的杂芳香族基团的碳原子或氮原子取代,并进一步被选自二苯并呋喃、二苯并噻吩、芴或咔唑的基团取代。
