Paragraph 0042-0045, (2020/06/16)
The invention discloses a host compound applied to the field of organic electroluminescence and an organic electroluminescence device using the compound. The molecular structure of the organic compound is as shown in a general formula 1 which is described in the specification. In the structural formula 1, Ar1 is independently selected from the group consisting of H and substituted or unsubstitutedC6-C60 aryl or heteroaryl groups, and the heteroaryl group contains at least one heteroatom selected from B, N, O, S, Si and P; X is independently selected from O, S, Se, C(R), Si(R), NR, P(=O)R and a carbonyl group, and R is selected from H, CN, C1-C8 alkyl groups and C6-C60 aryl or heteroaryl groups; A is independently selected from substituted or unsubstituted structures as shown in thespecification; and R and R are selected from H and C1-C8 alkyl groups. The host compound has good thermal stability, deep HOMO and shallow LUMO, can balance transfer of holes and electrons, is more sufficient in energy transfer, and can effectively improve the efficiency and prolong service life of the device.
