Fig. 1. UV/Vis absorption spectra of (a) ligands 3b–k; (b) previously reported 6 and [Ru(bpy)3]2+ as reference complexes for mononuclear 4a and bis[Ru(ii)-pyrrolide] triad 4b; and (c) mononuclear 4a and bis[Ru(ii)-pyrrolide] triads 4b–k. (d) Phosphorescence emission spectra for mononuclear 4a and bis[Ru(ii)-pyrrolide] triads 4b–k (collected in Ar using λex max). Absorption and emission spectra were collected on the PF6– salts of the complexes (5 μM) in MeCN.
