| titleOfInvention | A spirodimethyl anthracene fluorene organic compound and its application in organic electroluminescent devices |
| abstract | The invention relates to a spirodimethyl anthracene fluorene organic compound and its application in an OLED device. The spiro dimethyl anthracene fluorene is taken as the core, and substituted or unsubstituted: phenyl, biphenyl and bis-phenyl groups are connected through N atoms. , terphenyl, naphthyl, dimethylfluorenyl and dibenzofuranyl. The compound of the present invention has high glass transition temperature, high bond dissociation energy and excellent electrochemical stability, so it can improve the service life of OLED devices; the compound of the present invention also has a deep HOMO energy level, which can be used as a The hole transport/electron blocking layer material can effectively block the transfer of electrons or energy from the light-emitting layer to the side of the hole layer, thereby improving the recombination efficiency of holes and electrons in the light-emitting layer, thereby improving the light-emitting efficiency of OLED devices. |
