Picosecond absorption studies on the excited state of (.mu.-oxo)-bis[(tetraphenylporphinato)iron(III)] Academic Article uri icon


  • We have measured the kinetics and spectra of the intermediates of (μ-oxo)bis[(tetraphenylporphinato)iron(III)] in various solvents. The spectra of the intermediate species were measured at various intervals of time from -100 to 4.3 ns after excitation with a 532- or 355-nm 25-ps pulse. The intermediate state, possibly a cation radical, was assigned to a monomer that forms the photodissociated pair TPPFeII+ + TPPFeIII-O- and yields a small amount of disproportionation reaction products, FeIITPP and TPPFeIV=O. © 1988, American Chemical Society.
