Abstract We describe a procedure to suspend single walled carbon nanotubes with poly(3‐dodecylthiophene‐2,5‐diyl) and to purify them using density gradient centrifugation with 2,4,6‐tribromotoluene or dodecyloxy‐2,4,6‐triiodobenzene as density gradient medium. In contrast to fluorene‐based polymers, ( n , m ) selective solubilization is not observed.
