DOI: 10.1002/pi.5419

Abstract: For the first time, imino chemistry is explored for the synthesis of main chain fullerene oligomers and low-molecular-weight polymers. Oligo(aziridinofullerene)s and low-molecular-weight poly(aziridinofullerene)s (PAFs) are prepared by 1,3-dipolar cycloadditions of bis(azidoalkyl) comonomers to C60. The… read more here.
