Long-life organic electroluminescent compound and organic electroluminescent device comprising same

The invention provides a long-life organic electroluminescent compound and an organic electroluminescent device comprising the same. The structural general formula of the organic electroluminescent compound is as shown in a formula I in the specification. The organic electroluminescent compound contains a benzonaphthofuran fragment, dibenzofuran is replaced with a benzonaphthofuran structure, the conjugation length of pi electron cloud is prolonged, when molecules receive electrons and then are converted into an anion state, negative charges can be effectively dispersed on the benzonaphthofuran fragment, and therefore the organic electroluminescent compound has the advantages that the organic electroluminescent compound can be used for organic electroluminescence. According to the present invention, it is further found that the planarity of the benzonaphthofuran fragment is good, and the stability of the material can be significantly improved through the partial deuteration, such that the partial site on the
