Abstract
The present invention relates to diphenyl amine derivatives having luminescent properties, and particularly to diphenyl amines substituted with various electron-donating or electron-withdrawing groups. The compounds of the present invention show blue or blue-green luminescence, and luminescence of the compounds herein can be achieved by UV or visible light, thus being useful as a fluorescent dye or fluorescent material for an organic electroluminescence device or display.
