Semiconducting SWNT (sc-SWNT) has been successfully employed in many applications, such as photovoltaics, transistors, thermoelectric modules, and light emitters. To utilize sc-SWNTs as an active material in electronics, conjugated polymer wrapping method have been developed as a post-treatment approach to separate sc-SWNTs from the as-synthesized mixture. However, it is challenging to sort monochiral SWNT by this method. Different energies of sorted SWNTs from various chiralities act as energy barriers on charge transport. Therefore, improving the chiral selectivity of sc-SWNTs is critical for developing high-performance electrical devices. Here, we report the sorting technique of monochiral sc-SWNTs with large diameter depending on the backbone orientation of wrapping polymers for high performance-transistors.
