Compound containing naphthyridine derivative and application thereof

The invention discloses a compound containing a naphthyridine derivative and application thereof. The structure of the compound is shown in the specification, wherein X1 and X2 are independently C or N, and at least one is N; R1 is represented by -(L1)m-A1; R3-R6 are each independently represented by -(L2)n-A2, or adjacent groups combine with each other to form a substituted or unsubstituted ring; m and n are integers from 0 to 10; L1 and L2 are each independently a direct bond, a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group; A1 is a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; and A2 is hydrogen, deuterium, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group. The compound containing the naphthyridine derivative is high in refractive index, heat resistance and optical coupling efficiency, and when the compound is used for the organic electroluminescent device, the service life can be prolonged while low driving voltage is achieved.
