Supramolecular Interactions of High Molecular Weight Poly(2,7-carbazole)s with Single-Walled Carbon Nanotubes

A novel 2,7-carbazole monomer unit was synthesized and used to prepare two poly(2,7-carbazole)s, both of which were obtained in relatively high molecular weight and display excellent solubility in common organic solvents. The polymers were able to effectively disperse carbon nanotube bundles in both THF and toluene using a relatively simple procedure to yield concentrated polymer–carbon nanotube samples that were stable for months. The …
