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)‐ co ‐bithiophene (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.
