7-di(3,5-difluorophenyl)-1,10-phenanthroline), and [Ru(4,7-dfpphen)3 (AsF6 )2 ] (Ru-Fdpp) were synthesized, and their photophysical, electrochemical, and electroluminescent properties were studied systematically. The introduction of the electron-withdrawing group 3,5-difluorophenyl leads to a redshift of the emission of the ruthenium complexes. In addition, the 3,5-difluorophenyl substituent extends
