Abstract:
The present invention discloses a novel ditriphenylene derivative is represented by the following formula (I), the organic EL device employing the ditriphenylene derivative as host material or dopant material of emitting layer can lower driving voltage, prolong half-life time and increase the efficiency. Wherein m, n represent an integer of 0 to 10. X is a divalent bridge selected from the atom or group consisting from O, S, C(R3)(R4), NR5, Si(R6)(R7). Ar1, Ar2, R1 to R7 are substituents and the same definition as described in the present invention.
