Synthesis and photophysical and electrochemical properties of three novel Ru(II) complexes.

This paper on three heteroleptic {(bpy)2Ru[2-(perylen-3-yl)-1-H-imidazo[4,5-f][1,10]-phenanthroline)]}2+, {(bpy)2Ru[2-(pyren-1-yl)-1-H-imidazo[4,5-f][1,10]phenanthroline]}2+ and {(bpy)2Ru[2-(anthracen-10-yl)-1-H-imidazo[4,5-f][1,10]phenanthroline]}2+ complexes with perylene, pyrene and anthracene appended 1-H-imidazo[4,5-f][1,10]-phenanthroline as the diimine ligands is a further demonstration of the effect of extending the diimine ligands' π-system on the absorption and emission properties.
