An atom-economical approach to functionalized single-walled carbon nanotubes: Reaction with disulfides

Simple and effective exterior decorating: Single-walled carbon nanotubes were functionalized with disulfides, including cystamine-core polyamidoamine dendrimers, simply upon heating in toluene (see picture). One advantage of this method is that any unreacted disulfide can be recovered by filtration. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
