Abstract
The irradiation of Cu(10-methyl-1,4,8,12-tetraazacyclopentadecan-10-NO2)X+, X = halide, HCO2â, CH3CO2â and C6H5CH2CO2â, in deaerated CH3CN or CH3OH at 350 nm resulted in the reduction of the pendent î¸NO2 to î¸NO. Flash photolysis revealed the formation of the nitroso products via the photo-induced oxidation of the axial ligand Xâ. Intermediates in a 10 ns-1 s time scale have been tentatively assigned as species formed by the addition of the X radicals to the î¸NO2. Similar redox processes were observed when the irradiation of the complexes was carried out in the ligand field band, λexc = 560 nm. Conversion of the ligand field excited states to Xâ to Cu(II) charge transfer excited state account for the photoreactivity of the former excited states.
