摘要

The oxidative reactivity of THF derivatives formed during THFC_(60) synthesis was evaluated with indigo dye as a model compound. The results showed that the formation of previously undetected oxidizing agents during THFC_(60), synthesis accounted for the degradation of indigo dye by THFC_(60) (THFC_(60)/unwashed), while THFC_(60) after vigorous washing (THFC_(60)/washed) and nC_(60) prepared without the use of THF were not reactive. γ-Butyrolactone (GBL) was detected by GC-MS in the THFC_(60)/unwashed as one of THF derivatives, but showed no reactivity with indigo dye. An organic peroxide was detected in the THFC_(60)/unwashed by HPLC,and was reactive with indigo dye. This compound was found to also account for the elevated antibacterial and bactericidal activities of THF/ nC-(60)/unwashed on E, coli. Analysis by LC/(+ESI)MS and ~1H NMR showed that the detected THF peroxide was tetrahydro-2-(tetrahydrofuran-2-ylperoxy)furan, The formation of THF peroxide during the preparation of aqueous stable C_(60) aggregates provides another potential explanation for the reactivity and oxidative stress mechanisms of THFC-(60) system reported in the literature, although it does not exclude the potential reactivity and toxicity of nC_(60) itself.
