Investigation of Charge Transport Properties in ε-Branched Diketopyrrolopyrrole-Based Polymers for High-Performance Field-Effect Transistors |
| 초록 |
In molecular design of high performance polymer semiconductors, side-chain engineering has recently attracted great attentions due to easy modulation of intermolecular self-assembly and charge-carrier mobility by controlling the branching point of the side chain from the polymer backbone. Inspired by the effects of side-chain positions on the intrinsic properties of polymer semiconductors, herein we report a systematic investigation of the diketopyrrolopyrrole (DPP)-based π-systems incorporating novel ε-branched side chains. The developed polymers exhibited extraordinarily high electrical performance with both hole and electron mobilities superior to that of unipolar amorphous silicon. |
