Aqueous-Soluble N-type Conjugated Polymers for High-Performance Organic Electrolyte-Gated Transistors |
| 초록 |
Replacing toxic processing solvents with green solvents is one of the most pressing challenges for commercialization of electronic devices beyond industrial regulations. However, so-called green solvents still show harmfulness to both environment and human body. Herein, we fabricated water/ethanol-processed n-type organic electrolyte-gated transistors (OEGTs), utilizing naphthalene diimide-based polymers with different side chains. To impart the processability in ethanol/water mixture, branched oligo ethylene glycol side chains were attached to the NDI backbone. Depending on the length of side chains, aggregation behaviors and crystalline characteristics of the polymers could be systematically controlled. As a result, the highest electron mobility of 0.1 cm2 V-1 s-1 was obtained in P(NDITEG-T)-based OEGTs, which is among the best performances of n-type aqueous-processed organic transistors to date. |
