Synthesis, aggregation behavior, and photodynamic properties of a water-soluble fulleropyrrolidine bearing an N-PEG pyridinium unit

Abstract

Herein, we describe the synthesis of a water-soluble photodynamically active fullerene bearing a polyethylene glycol chain and a hydrophilic cationic group, revealing that the solubility of the above derivative in aqueous medium depends on ultrasonication time, with the particle size of aggregates being correlated with concentration.
