Abstract

The present disclosure relates to a nitrogen heterocycle fused ring-indene compound having a structure represented by the Formula (I), in which Ar1 represents a substituted or unsubstituted aromatic fused ring group containing at least one nitrogen heteroaryl; Ar2 represents a chemical group acting as an electron donor; R1 and R2 are independently selected from the group consisting of hydrogen, substituted or unsubstituted C1-C20 alkyl, substituted or unsubstituted C3-C20 cycloalkyl, substituted or unsubstituted C1-C20 alkoxy, substituted or unsubstituted C3-C20 heterocyclyl, substituted or unsubstituted C6-C40 aryl, and substituted or unsubstituted C5-C40 heteroaryl. The compounds according to the present disclosure have high glass transition temperature and thermal stability, and are easy to form a high-quality amorphous film, so that a driving voltage can be lowered, the luminous efficiency and lifetime of the device are improved.
