Physical Chemistry


The low quantum yields of photoconversion of phenols and the low probability of formation of phenoxy radicals in solid polymers indicate significant cage effects. An increase in the degree of shielding of the hydroxyl group results in an increase, while incorporation of electron-acceptor substituants in the p position results in a decrease in the reactivity of the phenols in the polymers. The increase in the quantum yields of photoconversion and the decrease in the quantum yields of the fluorescence of phenols with a decrease in the wavelength are due to the occurrence of a reaction and induced radiationless deactivation with the participation of higher excited states.
