In this work, a simple and rapid method to selectively sort semiconducting-SWCNTs (sc-SWCNTs) with large diameters using poly[2, 7-(9, 9-dioctylfluorene)-alt-4, 7-bis (thiophen-2-yl) benzo-2, 1, 3-thiadiazole] (PFO-DBT) is presented. The sorted sc-SWCNTs inks have been directly used to fabricate thin film transistors (TFTs) by aerosol jet printing. Printed TFTs with effective mobility ~15.6 cm2·V-1·s-1 and on/off ratio ~107 have been achieved. In addition, all the printed devices exhibited rapid photocurrent response to light irradiation. TFTs based on PFO-DBT sorted sc-SWCNT exhibit good photoresponsive characteristics with good stability and rapid response.
