Complexation of these ligands to Ru(II) afforded diastereomerically pure Delta and Lambda isomers, as verified through circulardichroism and circularly polarized luminescence spectroscopy. Ligands (+)-L2 and (-)-L2 were further coordinated to Zn(II) to form a complex with intriguing photophysical properties. Whereas Zn(bpy)32+ was shown to be a fluorescent emitter outside the visible spectrum, the
