Semiconducting single-walled carbon nanotubes (s-SWCNTs) are considered to be the most promising candidates for high-performance field-effect transistors (FETs). In the present study, a new type of conjugated copolymer containing peri-Xanthenoxanthene and carbazole units, named PCzPXX, has been synthesized and used for selectively sorting SWCNTs. The solution form of sorted SWCNTs has been used to fabricate TFTs by dip-coating method. These TFTs exhibited p-type behaviors with charge carrier mobility as high as 5.5 cm2/Vs and on/off current ratio of 107 without any 'burn-off or post-treatment.
