Fully Degradable n-Type Conjugated Polymer for High-Performance and Transient Organic Electronics |
| 초록 |
In this study, 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 (fIM = 0.45), PNDIT2/IM-0.45 film exhibits a high electron mobility (µe) of 0.04 cm2 V-1S-1 in organic field effect transistor (OFET), demonstrating excellent potential in the application of transient OFET. Thus, this study provides the useful guideline for the design of n-type degradable CPs and establishes the important correlation between the molecular structure-electronic performance-transient properties. |
