Abstract:
It is an object to provide a new compound which is suitable for a material of an electron-transporting layer of a light-emitting element. In particular, it is an object to provide a compound which can be used for forming a light-emitting element capable of emitting light at a low drive voltage. An acenaphthopyridine derivative represented by the following general formula (G1) is provided. In the formula, Het represents a pyridyl group or a quinolyl group.
