Naphthyl-substituted anthracene derivatives and their use in organic light-emitting diodes

摘要

The present invention relates to anthracene derivative compounds represented by Formula I:or a pharmaceutically acceptable salt thereof, with R₁, R₂, R₃, R₄, L, X, a, b, and c defined herein. The compounds of the present invention, having a substituted silicon atom introduced in anthracene, advantageously improves the solubility of anthracene without any adverse effects, thereby allowing solvent-processing. Also disclosed are light emitting materials comprising such compounds, the use of such light emitting materials, and organic light emitting devices comprising such light emitting materials.
