Fluorene compound and organic electroluminescent device using the same |
摘要 |
The present invention discloses a new fluorene compound and organic EL device using the compound. The organic EL device employing the new fluorene compound as host material can lower driving voltage, prolong half-lifetime. The fluorene compound can functions as blue emitting host material of a light emitting layer and improve CIE color purity in blue emitting device. The fluorene compound are represented by the following formula(A):;
Wherein R1 to R6 are identical or different. R1 to R6 are independently selected from the group consisting of a hydrogen atom, a halide, alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms, a substituted or unsubstituted heteroaryl group having 6 to 30 carbon atoms. R7˜R13 are identical or different R7 to R13 are independently selected from the group consisting of hydrogen atom, halide, alkyl group, aryl group, heteroaryl group. m and n are independently an integer of 0 to 3, X is selected from carbon or nitrogen. |
