Short Communication: Stability of C70O in Toluene

C70O dissolved in toluene transforms to as yet undetermined compounds when exposed to light at room temperature. After 140 days, only 21% of the original C70O remained. C70 was not formed. C139, or C140O were not found. One possible explanation is that the compounds formed were very insoluble in toluene and that their solids either remained in colloidal solution or attached themselves to the glass walls of the container bottles.
