Full steam ahead: Highly selective and versatile syntheses of aza[60]fulleroids and aziridino[60]fullerenes from C60, which utilize N,N-dihalosulfonamides as an N1 source, were developed. Photophysical, electrochemical, and thermal properties of the iminofullerenes were measured, and photovoltaic cells based on these compounds were fabricated. The power conversion efficiencies (PCEs) of the devices show moderate values ranging from 1.33 to 2.35 % (see scheme).
