Water/Ethanol Processable N-type Semiconducting Polymers for High Mobility Electrolyte-gated Transistors |
| 초록 |
Replacing toxic processing solvents with eco-friendly ones is one of the most pressing challenges for commercialization. Herein, we demonstrated water/ethanol-processed n-type organic electrolyte-gated transistors (OEGTs), utilizing naphthalene diimide-thiophene (NDI-T)-based polymers with the different side chains. To impart the ease of processability in the mixture of ethanol and water, oligo ethylene glycol (OEG) side chains were attached to the NDI backbone. Depending on the length of side chains, aggregation and crystalline behaviors of the polymers could be finely controlled. As a result, the highest electron mobility of almost 0.1 cm2V-1s-1 was obtained in P(NDITEG-T)-based OEGT, which is one of the best performances of n-type aqueous-processed organic transistors. |
