a Normalized X-ray photoelectron spectrum of polyOsRuFe showing N (1s), Os2+ (4f), Ru2+ (3d), and Fe2+ (2p) bands. b Change in color in the solution state upon the stepwise complexation of Os(II) in TOsT, followed by Ru(II) in TOsRuT and Fe(II) in polyOsRuFe. c UV–vis spectra of TOsT, TOsRuT (both solutions were 5 × 10−6 M in CH2Cl2/CH3OH; 1/1, v/v), and polyOsRuFe (5 × 10−6 M in DMSO). d Cyclic voltammograms of polyOsRuFe at scan rates of 0.01–0.1 V/s in a three-electrode system, electrolyte: 0.1 M LiClO4 in CH3CN.
