Water-soluble C60– and C70–PVP polymers for biomaterials with efficient 1O2 generation

Abstract

Highly water-soluble fullerene polymers were successfully prepared by a simple direct free-radical copolymerization of N-vinylpyrrolidone and intact C60 or C70 as a radical-capping agent. Using AIBN as a radical initiator, the polymers (C60- or C70-PVP) with significantly high molecular weight (~30 kDa) and with efficient (1)O2 generation were obtained.
