摘要
高分子半导体材料具有性能易调控、可溶液加工、柔性可折叠等优点,是柔性电子的最理想材料。然而,传统合成方法造成高分子半导体材料批次差异大、单体自偶联缺陷多,因此限制了高分子半导体材料的大规模商业化应用。本文重点阐述共轭交替高分子中单体自偶联缺陷对材料光电性能的影响,旨在揭示共轭高分子精准合成的重要性,为高性能共轭聚合物材料的精准、宏量制备提供新思路,并推动其产业化应用的进程。
Semiconducting polymers,especiallyπ-conjugated donor-acceptor(D-A)copolymers with defect-free alternating structures,are essential materials for plastic electronics and optoelectronics owing to their tunable chemical structures,tunable bandgaps and optical absorptions,excellent charge transport mobility,mechanical flexibility,and solution processability for printing.However,traditional synthesis methods may cause homocoupling structural defects,resulting in large batch variations,thus hindering the large-scale commercial application of polymer semiconductors.This study reviews the effect of homocoupling structural defects of conjugated polymers on their photoelectric properties,aiming to reveal the importance of precise synthesis on the performance of conjugated polymers.We believe this review will guide the precise and large-scale production of high-performance polymers,potentially catalyzing advancements in their industrial applications.
