AROMATIC COMPOUND DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

The present invention relates to an aromatic compound derivative and an organic electroluminescent device using the same, specifically to an aromatic compound derivative denoted by chemical formula 1 and an organic electroluminescent device using the same. In chemical formula 1, L1-L4 and X1 are a substituted or non-substituted aryl group with a specific structure, independently, and R1 is a hydrogen atom and an alkyl group in which groups adjacent to each other are combined to each other for forming a saturated or unsaturated carbon ring.
