Abstract:
A compound having a structure wherein at least 8-position or 9-position of fluoranthene is replaced by a nitrogen atom, a material for organic electroluminescence devices including the compound, and an organic electroluminescence device and an electronic equipment each including the material are provided. The compound is represented by formula (1): wherein A represents CR0 or N; R0 to R8 each independently represent a hydrogen atom or a substituent; at least one selected from R0 to R8 represents a substituent other than hydrogen atom; and groups selected from R0 to R8 which are bonded to adjacent carbon atoms may be bonded to each other to form a saturated or unsaturated ring structure.
