Acceptor-Acceptor-Type Conjugated Polymers for Energy Level Modulation in Semiconducting Carbon Nanotube Transistors.

ABSTRACT: Numerous methods have been developed for sorting single-walled carbon nanotubes (SWCNTs), and polymer wrapping has become one of the most widely applied strategies for obtaining high-purity semiconducting SWCNTs (s-SWCNTs). Conjugated polymers can selectively sort s-SWCNTs, yet the role of frontier orbital level tuning in this process remains underexplored. In this study, we designed and compared four naphthalene diimide (NDI)-based copolymers with distinct backbones. Among them, the NDI-copolymers with a bithiophene donor (PNDI-2T) or a bis(thienyl)imide acceptor (PNDI-BTI) can effectively wrap onto the s-SWCNTs for investigating how modulation of the frontier energy levels affects polymer-nanotube interactions and device performance. Optical characterizations revealed that PNDI-BTI achie
