Drastic change in the rate of photochemical rearrangement of 1,6-(N-phenyl)aza-[60]fulleroids by switching the excited states through simple methyl substitution on the phenyl group

The reaction rate for the photochemical rearrangement of azafulleroids to aziridinofullerenes differed ca. 3000-fold depending on the number and position of the methyl substituent(s) on the N-phenyl group.
