Ru(II) complexes with new redox-active 1,10-phenanthroline derivatives: structural, spectral, and electrochemical investigations

New 1,10-phenanthroline derivatives bearing diarylamino and heteroaromatic moieties in the 3,8-position have been prepared by a palladium-catalyzed C–N bond formation reaction. Formation of Ru(II) complexes with the chelating ligands and their photophysical and electrochemical redox properties have been examined.
