“…Nowadays, there is significant interest to successfully develop high efficiency separation routes. Those techniques are based on the differences in physical and chemical properties and they involve methods such as electrophoresis 5, 6, chromatography 7, 8, density gradient ultracentrifugation (DGU) 9, 10, or selective destruction/functionalization 11, 12.…”

In this contribution, we present preliminary results from an optical absorption and resonance Raman spectroscopic investigation on single-walled carbon nanotubes (SWCNT) functionalized by poly(9,9-dioctylfluorenyl-2,7-diyl)-cobithiophene (PFO-BTP). A route for a stable suspension of SWCNT in a solution of fluorine-base copolymer is shown. Additionally, the detailed analysis of the supernatant and sediment after centrifugation of the functionalized sample is given. The resonance Raman and optical absorption spectroscopic data suggest that selective wrapping of the carbon nanotubes by PFO occurs. Additionally, one can see that the abundance of SWCNT in the supernatant in a bulk sample increased by a factor of 2.

The status of SWNT purification sciences within the last two decades are reviewed. Over the years, the aggressive search for effective and efficient post-synthetic purification technique has given rise to the development of numerous methods. Unfortunately, most of these methods do not possess the potentials of being selective, scalable, nor effective. On the other hand, the mechanisms behind the promising separation methods are yet to be fully understood. For such techniques, it is recommended that interest should now lie more on investigating the underpinning mass transfer kinetics and equilibrium thermodynamics with a view to making them more efficient.
