We develop a series of n-type fully-degradable CPs, naphthalene diimide (NDI)-based terpolymer (PNDIT2/IM-x). The incorporation of imine linker (IM) into the conjugated polymer backbone of NDI affords the capability of facile hydrolysis degradation while maintaining efficient π-conjugations and high electrical properties. Additional benefit of this molecular design is systematic tunability of the degradation characteristics and electrical performance depending on IM content (fIM). At the optimal point that afford the complete degradation of PNDIT2/IM-0.45 film under acidic condition, PNDIT2/IM-0.45 film exhibits a high electron mobility in organic transistor, demonstrating excellent potential in the application of transient electronics. High µe value is mainly attributed to the enlarged edge-on orientations of PNDIT2/IM-x crystallites with very tight stackings. Thus, this study provides the useful guideline for the design of n-type degradable CPs.
