Single-electron reduction of C60 with a carbon radical: formation of the Crystal Violet cation–fulleride ion salt†
Abstract
Whereas many carbon radicals are known to add to C60, the reaction of Crystal Violet radical 1• with C60 resulted in single-electron transfer, leading to a carbocation–carbanion salt 1+C60•–: the product was isolated as microcrystalline powder and was characterized by EPR, VIS-NIR and NMR spectroscopy.
