The purity of Single-Walled Carbon Nanotubes (SWNTs) is a key parameter for their integration in electronic, optoelectronic and photonic devices.Samples of pristine SWNTs are inhomogeneous in terms of electric behavior and diameter and contain a variety of amorphous carbon and catalyst residues.To obtain high performance devices, purification of SWNTs is required.Conjugated polymers have emerged as efficient solubilizing and sorting agents for small diameter SWNTs (HiPco tubes, 0.7 nm<Φ<1.1 nm).Nevertheless, large diameter SWNTs with Φ>1.1 nm are not efficiently sorted using existing polymers.
