Abstract

Intermediates stabilized in γ-irradiated mono-and dibenzosubstituted crown ethers are studied by ESR spectroscopy at 77 K. PhO radicals and radicals with H-atom abstraction from polyether ring are the main products at low temperature γ-radiolysis. The nature of radicals produced in radiolysis and the yield of radicals,G_R depend on macroring size and on the number of aromatic substiuents. Negative deviation from additive in function ofG_R versus ε of substituents is an evidence of efficient transfer of adsorbed energy to the π-system of aromatic group.
