제목 Fully Degradable n-Type Organic Semiconductors for High-Performance and Transient Organic Electronics
초록 The degradable organic semiconductors have significant potentials for the transient and biomedical organic electronics, but there have been only few studies of fully-degradable conjugated polymers (CPs). In addition, these examples are limited to p-type CPs. Herein, 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 backbone of NDI affords the capability of hydrolysis degradation while maintaining efficient π-conjugations. Additional benefit of this molecular design is tunability of the degradation and electrical characteristics depending on IM content (x). At the optimal point, the transient organic field effect transistor (OFETs) of PNDIT2/IM-0.45 exhibits a high mobility (µe) of 0.04 cm2 V-1S-1 and demonstrates fully degradations under acidic conditions. High µe value is attributed to the enlarged edge-on orientations with very tight stackings.
