研究领域

高效分子半导体材料的设计合成与表征分子半导体由于具有优异的光电性能，以及柔性、轻薄、可溶液加工等性质，而被学术界和工业界认为可应用于太阳能电池、晶体管、可穿戴设备等电子器件。其器件性能与其分子结构、聚集态结构及其在器件中的排列和分布都有着密切关系，我们通过调控这些结构和排布来提高其器件性能。基于分子半导体的功能墨水制备与应用廉价的溶液加工如喷涂、打印，是分子半导体相对于无机半导体的优势之一。如何制备具有特定结构的高性能分子半导体溶液，即功能墨水，是其将来工业化生产必不可少的技术壁垒之一。分子半导体与绝缘体复合材料的研究分子半导体多为共轭分子，受限于目前的合成方法，难于被精准、高效、大批量、低成本合成。且其半刚性分子结构使其薄膜力学性能较差。而常见的高分子为绝缘体，如PE、PS、PEG等，具有廉价、透明、力学性能好、可生物相容等可与分子半导体互补的性质。因此我们通过选择性的共混分子半导体与绝缘体来制备性能更多更优的复合材料。
