An anthracene derivative represented by general formula (I):
1
wherein X and Y represent a trifunctional aromatic ring group or the like, (1) A
1
to A
4
represent an aryl group or a monovalent heterocyclic group or (2) A
1
and A
3
represent hydrogen atom and A
2
and A
4
represent a styryl group in which the phenyl portion may be substituted and the &agr;-position or the &bgr;-position of the vinyl portion may be substituted with an alkyl group, R
1
to R
16
represent hydrogen atom, a halogen atom, cyano group, nitro group; alkyl group or the like, Q represents an arylene group or the like and p represents 0, 1 or 2; and an organic electroluminescence device which comprises at least an organic light emitting layer disposed between a pair of electrodes and the above anthracene derivative.
The novel anthracene derivative exhibits a high efficiency of light emission and excellent heat resistance when the derivative is used as a material constituting an organic electroluminescence device.
