Green-Solvent-Processable High-Mobility Semiconducting Copolymers with Engineered Oligo(Ethylene Glycol) Side Chains |
| 초록 |
Replacement of toxic chlorinated solvents with eco- and human-friendly green solvents is an important task for the successful implemention of next-generation polymer electronics technology. Herein, we synthesized five aqueous-solvent-processable conjugated copolymers by incorporating linear or branched oligo(ethylene glycol) side chains and systematically investigated their material and electronic properties. The resulting benzothiadiazole-based copolymers were well-soluble in both an ethanol/water mixed solvent, and their thin films showed distinct morphologies and crystalline characteristics that resulted from the self-assembling properties of the engineered side chains. Moreover, the copolymers showed excellent electrical characteristics with high hole mobilities of up to 0.1 cm2 V-1 s-1. These results clearly demonstrate the immense potential of branched oligo(ethylene glycol) side chains for application in green electronics. |
