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

The invention discloses 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 partially deuterated aryl-substituted dibenzofuran fragment, meanwhile, it is also found that a weak fragment of a host material compound in an anionic state is located on dibenzofuran, the fragment is good in planarity, and by inhibiting vibration of partial sites of the dibenzofuran, the organic electroluminescent compound can be used for preparing a novel organic electroluminescent material. According to the invention, deuteration is carried out on a part of sites on a dibenzofuran structure, vibration of carbon-hydrogen bonds is reduced, the stability of benzofuran is significantly enhanced, an aryl substituent group is introduced to the dibenzofuran structure, the conjugation length of pi electron clou
