摘　　要：Monochiral single-walled carbon nanotubes(SWCNTs)can enable high-performance carbon-based electronic devices and integrated circuits.However,their fabrication often requires complex SWCNT purification and enrichment.Herein,we showed that isoindigo-based polymer derivatives(PDPPIID and PFIID)directly enriched(9,8)nanotubes from as-synthesized SWCNT powders selectively and efficiently to yield high concentration(9,8)nanotube inks.The selective wrapping mechanism was elucidated by classical full-atomistic molecular dynamic(MD)simulations.Thin-film transistors(TFTs)were fabricated by depositing the SWCNT ink into device channels using aerosol jet printing.TFT performance was strongly influenced by polymer residues,the deposition condition(humidity),and ink concentration.Optimized TFTs showed excellent device-to-device uniformity with 108 on/off ratios.Further,optoelectronic transistors were fabricated,and their photoelectrical neuromorphic characteristics,storage,memory,and logic functions were characterized under the pulsed light and voltage stimulations,demonstrating excellent application potentials.
