摘要：
Paramagnetic products stabilized in both 4,4′(5′)-di-(tert-butylcyclohexano)-18-crown-6 (DtBuCH18C6) and its solution in 1-octanol upon low temperature (77 K) X-rays irradiation were studied by ESR spectroscopy. Macrocyclic –O–ĊH–CH2– radicals and acyclic O = C(H)–ĊH–O– radicals were found as main radiolysis products in neat DtBuCH18C6. Fraction of acyclic radicals resulting from the macrocycle cleavage was about 50%. No radical products resulted from t-Bu and cyclohexyl fragments were observed. It was concluded that the primary events were essentially concerned with ionization of the polyether moiety. Irradiation of frozen DtBuCH18C6 solutions in 1-octanol resulted in formation of radicals both from crown ether and alcohol.
