Summary:The invention belongs to the technical field of organic electroluminescence, and discloses a compound and an organic electroluminescence device.The structural general formula of the compound is as shown in the formula (1): # imgabs0 # formula (1); wherein: X is selected from NRa, CRbRc, O, S or Se; eT represents an electron withdrawing group; l is selected from a single bond, a substituted or unsubstituted arylene of C6-C60 or a substituted or unsubstituted heteroarylene of C3-C60; ring A is selected from a structure as shown in a formula (2) or a formula (3); # imgabs 1 # formula (2) # imgabs 2 # formula (3); x1-X12 are respectively and independently selected from CR0 or N; and two adjacent sites in X1-X4, X5-X6, X7-X8 and X9-X12 are fused with the five-membered ring containing X in the formula (1). The compound has the advantages of high optical and electrical stability, low sublimation temperature, low driving voltage, high luminous efficiency, long device service life and the like, and can be used as a re
