Many potential applications of carbon nanotubes require their manipulation or chemical modification. These tasks would be made easier if the nanotubes could be dissolved readily in common organic solvents without first having to modify their structure. Building on a recent report that highly polar solvents are attractive candidates, Bahr et al. have tested the solubility of unpurified nanotube samples produced by a gas-phase catalytic process in a range of organic solvents, some of which have been shown to be advantageous for dissolving fullerenes. Solubility was highest in 1,2-dichlorobenzene, followed by chloroform. The 1,2-dichlorobenzene solution (or suspension) was stable for 3 days. It remains unclear whether the nanotubes are completely separated or are present as small bundles or ropes. — JU
