The photochemistry of the complexes [Fe(N4Py)(CH3CN)](ClO4)2 (1) , where N4Py is (1,1-di(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine) and [Fe(MeN4Py)(CH3CN)](ClO4)2 (2), where MeN4Py (1,1-di(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)ethanamine), in water, dichloromethane and methanol, is described. Under UV or visible irradiation visible irradiation both 1 and 2 undergo enhancement of the rate of outer sphere electron transfer to 3O2 to yield the superoxide radical anion and the complexes in the Fe(III) redox state. Addition of ascorbic acid to the photoproduct leads to a recovery of the initial UV/Vis spectrum of 1 and 2, indicating that ligand oxidation does not occur.
we should learn to make this ligand. The Npy4 theme would be good literature talk.
