Formation of C60 radical cation in iron(III)-exchanged zeolite Y

Article abstract of DOI:10.1246/cl.1997.875

When C₆₀ is introduced into the Fe³⁺-exchanged zeolite Y sample, an intense ESR signal at g = 2.0027 is observed. The ESR signal is due to the formation of C₆₀ radical cation (C₆₀^?+), since the signal intensity increases with an increase in the amount of Fe³⁺ loaded in the zeolite. Addition of perylene into the C₆₀^?+-zeolite system results in electron transfer from perylene to C₆₀^?+ to produce perylene radical cation accompanied by the disappearance of C₆₀^?+.
