Abstract
There is disclosed a substituted anthryl derivative is represented by the following general formula (1). The use of the substituted anthryl derivative allows the production of an organic electroluminescence device showing an extremely pure luminescence hue, and an optical output with high luminous efficiency, high luminance, and long life
