Synergetic Evolution of DPP-Based Polymeric Semiconductor for High Reproducibility and Performance |
| 초록 |
A new random copolymer consisting of similarly shaped D-A building blocks of DPP-SVS and DPP-TVT is designed and synthesized. The resulting P-DPP-SVS(5)-TVT(5) with an equal molecular ratio of the two building blocks produced significantly enhanced solubility when compared to that of the two homopolymers, PDPP-SVS and PDPP-TVT. This unique property produces a high charge carrier mobility of 1.23 cm2V−1s−1 of PDPP-SVS(5)-TVT(5), as determined from organic thin film transistor (OTFT) measurements. The high solubility of PDPP-SVS(5)-TVT(5) promotes formulation of high-viscosity solutions which could be successfully processed to fabricate large-areal OTFTs onto hydrophobically treated 4 in. wafers. This result shows that producing devices with extremely narrow distribution of OTFT parameters. This is the first study to report on successfully realizing large-areal reproducibility of high-mobility polymeric semiconductors. |
