Abstract

original image

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.
