Naphthyl the anthracene derivative which is substituted and the use in the organic light-emitting diode

摘要

The present invention relates to anthracene derivative compounds represented by Formula I: or a pharmaceutically acceptable salt thereof, with R 1 , R 2 , R 3 , R 4 , 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.
