Figure 7

(a) Ultraviolet-visible spectrum of a deoxygenated aqueous solution of Mn(III)TPyP (10 μM) and FMN (10 μM; black trace) and its evolution for 1 h after addition of NADH (4 equiv.) at 20 °C (red trace). (b) Ultraviolet-visible spectrum of a deoxygenated aqueous solution of Mn(III)TPyP (10 μM) and FMN (10 μM) in the presence of the modified polymer (250 μM in monomer; black trace) and its evolution for 2 min after the addition of NADH (4 equiv.) at 20 °C (red trace). (c) Ultraviolet-visible spectra of a deoxygenated 10-μM aqueous solution of the reduced Mn(II)TPyP (10 μM) with FMN (10 μM; red trace) and its evolution for 6 min on exposure to O2 at 20 °C (black traces).
