ε-Branched Side Chain Substituted Diketopyrrolopyrrole-based Random Terpolymers for High-Performance Organic Transistors |
| 초록 |
Various recent papers have reported that both the backbone and side chains constituting semiconducting polymers have significant effects on the performance of the organic field-effect transistors (OFETs). Donor-acceptor (D-A) conjugated polymers based on diketopyrrolopyrrole (DPP) have frequently been utilized as backbones for high-performance OFETs. Our groups previously reported two ε-branched side chain substituted D-A polymers, PDPP-selenophene (SE) and PDPP-(E)-2-(2-(thiophen-2-yl)vinyl)thiophene (TVT), which exhibited different physical properties. In this work, random terpolymers composed of DPP-SE and DPP-TVT with various composition ratios of 7:3, 5:5, and 3:7 have been synthesized and investigated to evaluate their optical and electrical characteristics. This study will provide guidelines for the facile control of charge transport and solubility by changing the composition of terpolymers. |
