Paragraph 0126; 0127; 0130, (2019/01/08)
The invention provides a compound, which is shown as a following general formula (I) or (II) in the specification, wherein, X is selected from CR 4 or N; R 1 to R 4 are respectively and independentlyselected from hydrogen, C1-C10 alkyl groups, substituted or unsubstituted C5 -C60 aryl or heteroaryl groups, the substituent of aryl or heteroaryl groups is selected from deuterium, fluorine, methyl group, methoxy group, cyano group, phenyl group, biphenyl group, naphthyl group, phenanthryl group, and substituted or unsubstituted anthracyl group, the substituent of the anthracyl group is selectedfrom the group consisting of phenyl, biphenyl, terphenyl, naphthyl, and phenanthryl; and a dotted line and Cy in the general formula (II) represent a five- or six-membered aromatic or heteroaromatic ring fused to a pyrimidine ring. The compound can be used in an organic electroluminescent device. The invention also provides an organic electroluminescent device comprising the above compound.
