Abstract

The invention provides a novel compound having a structure represented by formula (I). In the formula (I), R1 to R5 are respectively independently selected from C1-C20 aliphatic alkyl groups or C6-C20 aromatic groups; Ar is selected from C4-C30 aromatic rings, C4-C30 N-containing heterocyclic rings, C4-C30 condensed heterocyclic aromatic hydrocarbons, C4-C30 arylamino groups or C4-C30 aryloxy groups; n is 1 or 2; A1 to A4 are N atoms or C atoms, A2 and A4 are the C atoms when the A1 and the A3 are the N atoms, or A2 and A3 are the C atoms when A1 and the A4 are the N atoms, or A1 and A3 are the C atoms when A2 and A4 are the N atoms, or A1 and A2 are the C atoms when A3 and A4 are the N atoms, or A2 is the C atom when A1, A3 and A4 are the N atoms; and L is a singly-bonded or C6-C10 aromatic ring or a C4-C10 N-containing heterocyclic ring. The compound is used in organic electroluminescent devices as an electron transfer layer material or a luminescent host material.
