ABSTRACT:
There are provided a novel benzofluoranthene compound and an organic light-emitting device which uses the benzofluoranthene compound, gives a blue emission hue with extremely good purity, and has an optical output with a high efficiency, a high luminance, and a long life. Specifically, there are provided a benzofluoranthene compound represented by the general formula shown below and an organic light-emitting device including a pair of electrodes including an anode and a cathode one of which is a transparent or translucent electrode material, and an organic compound layer disposed between the pair of electrodes and including a material for an organic light-emitting device containing the benzofluoranthene compound.In the general formula (1), one of X1, X2, X3, X4, X5, and X6represents a substituted or unsubstituted fused heterocyclic group having four or less rings, and the others of X1, X2, X3, X4, X5, and X6each represent a hydrogen atom.
