The synthesis and physicochemical properties of a new class of BODIPY-based donor-acceptor π-conjugated polymers are presented. Solution-processed top-gate/bottom-contact (TG-BC) thin-film transistors on flexible plastic substrates exhibit air-stable p-channel activities with charge carrier mobilities as high as 0.17 cm(2) /V·s and current on/off ratios of 10(5) -10(6) , the highest reported to date for a BODIPY-based semiconductor. The results shown here indicate a significant charge-transport improvement (>10000×) in BODIPY-based polymeric semiconductors, demonstrating its potential in future organic optoelectronic applications.
本文报道了一类新型基于 BODIPY 的给体-受体π共轭聚合物的合成及理化性质。基于柔性塑料衬底的顶栅底接触（TG-BC）溶液处理薄膜晶体管表现出空气稳定的 p 型沟道性能，电荷载流子迁移率高达 0.17cm(2)/V·s，电流开关比达到 10(5) -10(6)，这是迄今为止报道的基于 BODIPY 的半导体中最高的。这里展示的结果表明，基于 BODIPY 的聚合物半导体的电荷输运性能得到了显著提高（提高了 10000 倍以上），这表明其在未来的有机光电应用中具有潜力。
