- W45260993 abstract "The object of this work was to study the influence of an electron-donor substituent (an amino group) in the phenalenone molecule on the efficiency of the photochemical generation of ketyl radicals and their roles in the process of the formation of irreversible photoproducts. The ESR spectra were obtained for radicals of phenalen-l-one and its amino derivatives generated in the irradiation of ethanolic solution of the compounds with visible light. From the initial rate of rise in the intensity of the ESR signal the relative quantum yields of the photochemical generation of radicals of the isomeric aminophenalenones in ethanol were determined. It was found that the efficiency of the photodegradation of aminophenalenones is influenced not only by the rate of photohydrogenation as the primary stage, but also by the kinetics of the subsequent dark and photochemical reactions." @default.
