NAPHTHYL-SUBSTITUTED ANTHRACENE DERIVATIVES AND THEIR USE IN ORGANIC LIGHT-EMITTING DIODES

摘要

The present invention relates to shown in anthracene derivative compound formula (I) or its pharmaceutically acceptable salt, wherein R1, R2, R3, R4, L, X, A, b and c are as defined herein. The anthracene that there is the compound of the present invention the silicon atom replaced to be introduced into, beneficially improves the dissolubility of anthracene without any adverse effects, so that solvent be allowed to handle. Further disclose the luminescent material comprising such compound, the purposes of this luminescent material, and the organic light emitting apparatus including these luminescent materials.
