ABSTRACT:
An organic electroluminescent material and a device using the same wherein the electroluminescent material is a charge transport indenofluorene selected from one of Formula (I) and Formula (II)wherein R and R′ are independently selected from the group consisting of a hydrogen atom, halogen atom, cyano, alky, alkoxyl, alicyclic alkyl, substituted or unsubstituted aryl or heteroaryl, and dialkylamino; m and n are numbers of 0 to 4; R1, R2, R5, and R6are independently selected from the group consisting of hydrogen, an alkyl, a substituted or unsubsituted aryl, or an heteroaryl, an alkoxy, and vinyl; R3and R4are independently selected from the group consisting of a hydrogen atom, halogen atom, alkyl, alkoxy, and substituted or unsubstituted aryl or heteroaryl; and p is 1 or greater.
