摘要：
The present invention discloses an novel organic material containing indenotriphenylene derivatives and organic EL device using the indenotriphenylene derivatives as hole blocking layer(HBL), electron transport layer(ETL) and/or phosphorescent host can efficiently lower driving voltage, lower power consumption and increase the efficiency. The present invention further relates to the methods of preparation for the indenotriphenylene derivatives and organic EL device comprising these derivatives.
