Figure 3.

UV–vis–NIR absorption spectra of MB-DIPY 4 (red) and its two-electron-oxidized [4]2+ (blue) and one-electron reduced [4]•– (green) derivatives obtained under spectroelectrochemical oxidation/reduction conditions in the deoxygenated 0.3 M TBAP/DCM system. The discontinuity at 850 nm reflects a detector change.
