Control of Molecular Structure for High-Performance Organic Thin Film Transistors and Organic Solar Cells in π-Extended Diketopyrrolopyrrole-based Polymers |
| 초록 |
Recently, diketopyrrolopyrrole (DPP)-based copolymers have attracted much attention due to the high hole mobility in thin film transistors (TFTs) and high power conversion efficiency in polymer solar cells (PSCs) made of solution processing technology. These copolymers containing the strong symmetric DPP acceptor and π-extended donor endow the high crystallinity, planarity, and intermolecular interaction. In this study, we have synthesized a series of DPP-based copolymers bearing more π-extended donanting units for high-performance organic TFTs and PSCs. Also, we systematically studied the effect of various donor units and donor length in these copolymers on the optical properties, film morphology, and device properties. |
