The invention relates to a benzocarbarzole derivative and an organic electroluminescent device using the benzocarbarzole derivative. The benzocarbarzole derivative has the advantages of being relatively high in Tg, difficult to crystallize and the like, and the benzocarbarzole derivative is suitable for manufacturing the organic electroluminescent device, especially as a light-emitting layer material or an electronic transmission material, and can improve the light-emitting performance of the organic electroluminescent device and prolong the service life of the organic electroluminescent device.
