This paper reports on fulleroid derivatives which exhibited unusual magnetic properties in NMR spectroscopy. Some of the properties express themselves as {open_quotes}shift reagent properties{close_quotes}. The authors also report on new fulleroid derivatives whose electrochemistry provides evidence for a new form of intramolecular electronic interaction typical of certain fulleroids. The consequence of the new concept are that the redox (electrochemical) properties of 9-fluorenyl-derived fulleroids can be modified at will. A simple Huckel calculation lends support to periconjugation between the fluorenyl and fullerene moieties of these fulleroids. This discovery opens the way to investigate substituent effects on fulleroids akin to the Hammet relation for benzenoid aromatics.
