Here, we report the proof-of-concept of using organized chirality-sorted SWCNTs via the alignment relay technique (ART), where iptycene molecules order the nanotubes through π-π interactions. Top gated field-effect transistors (FETs) were fabricated with aligned (10,3) chirality SWCNTs as channels to show an ION of 3.8 µA, an ION/IOFF ratio of 2.9×106, and a carrier mobility of 10.08 cm2/Vs, which is enhanced by two magnitudes of order compared with a bundled SWCNTs network channel. In addition, ART was applied to align commercially available semiconducting SWCNTs to fabricate a chemiresistive gas sensor that showed prompt detection of 4 ppm ammonia (NH3) with a sensitivity of 0.43 ± 0.04 %/ppm, demonstrating a general approach to align SWCNTs for applications in electronic devices.
