Abstract
A material for an organic electroluminescence device including an indenofluorenedione derivative shown by the following formula (I): wherein X1 and X2, which may be the same or different, are any of specific divalent groups; R1 to R10, which may be the same or different, are a hydrogen atom, an alkyl group, an aryl group, a heterocycle, a halogen atom, a fluoroalkyl group, an alkoxy group, an aryloxy group or a cyano group; and R3 to R6 or R7 to R10 may be bonded to each other to form a ring.
