Abstract Organic field-effect transistors (OFETs) have been under development for decades due to their potential utility in flexible, low-cost, large-area applications. In this study, we designed and synthesized a new asymmetric diketopyrrolopyrrole(DPP) polymer by Stille-coupling polymerization. This polymer has a high π electron superposition by introducing an electron donor compound and has an asymmetric arrangement and therefore has a high solubility with an increase in the free volume. This high solubility allows solution processes to be carried out in environmentally friendly non-halogenated solvents. Organic electronic devices using organic electronic devices can be applied to semiconductor devices because they have excellent charge mobility and excellent point ratio. |
