Fig. 2. Molecular structures of water-soluble Ir(iii) complexes: (a) [Ir(sppy)3]3−, (b) [Ir(dfppy)2(pt-TEG)]+, and (c) [Ir(bt)2(pt-TEG)]+. (d) The overlap between the emission of [Ir(sppy)3]3− (green spectrum), [Ir(dfppy)2(pt-TEG)]+ (blue spectrum), and [Ir(bt)2(pt-TEG)]+ (yellow spectrum) with the absorption of [Ru(bpy)3]2+ (red spectrum). (e) Scheme showing the reduction (Ered, left) and oxidation potentials (Eox, right) of the metal complexes involved within Ru@Beads/Ir systems (same colour code as in Fig. 2d). The dashed lines show the oxidation potentials of TPrA (right) and TPrA˙ (left).
