New Postfunctional Method To Synthesize C60-Containing Poly(ethylene oxide)

This article reports the detailed synthesis and structural characterization of two new C60-containing poly(ethylene oxide)s by a new postfunctional method. A predesigned amino end-functionalized poly(ethylene oxide) was prepared, and this reactive macromolecular intermediate was reacted with C60 molecules in chlorobenzene to yield the C60-containing poly(ethylene oxide)s. The molecular structures of the polymers were characterized with 1H-NMR, IR, and ultraviolet-visible spectra. The polymers exhibited good solubility in common organic solvents and water and were stable in air. © 2004 Wiley Periodicals, Inc.
