It is an object of the present invention to provide a pyrene derivative that is unlikely to crystallize and is superior in quality in the case of forming a film. In addition, it is an object of the present invention to provide a light-emitting element from which stable light emission can be obtained for a long stretch of time by using the pyrene derivative. n nA pyrene derivative represented by the general formula (1) is synthesized. By using vacuum deposition to deposit this material, a light-emitting element from which stable light emission can be obtained efficiently for a long stretch of time can be obtained. |
