✦ Synopsis

netic ionic liquid (MIL), specifically 1-butyl-3-methylimidazolium [FeCl 4 ], to single-walled carbon nanotubes (SWCNTs). Our magnetic-SWCNTs, based on molecular FeCl À 4 magnetic ion bound to cationic imidazolium which was covalently conjugated to the nanotubes, were found to have a strong magnetic response and be easily dispersed in an organic solvent, N-methyl pyrrolidone. MIL-based magnetic SWCNTs is superior to magnetic particlebased nanotubes since particles attached typically are much bigger than the nanoscale diameter of SWCNTs and are prone to aggregation, detachment and non-homogeneity.
