1. 含硼氮配位键的高分子电子受体材料

高分子太阳能电池常用电子受体材料是富勒烯衍生物PCBM，富勒烯衍生物对太阳光的吸收能力差，且生产能耗大，成本高，因此需要开发非富勒烯的电子受体材料。用高分子作为电子受体材料，不但具有太阳光吸收能力强，成本低的优点，而且可以大幅度提高形貌稳定性和机械性能。但是高分子电子受体材料的种类和数量非常少，我们提出用硼氮配位键（B←N）设计高分子电子受体材料。发现硼氮配位键可以将常见高分子电子给体材料转变为受体材料，而且发展出基于硼氮配位键的新型拉电子单元，用于构建高分子电子受体材料。该工作为受体材料的设计提供学术新思想和材料新体系。

2. 溶液加工型石墨烯电极界面材料

高分子太阳能电池活性层与电极之间的界面性质对于器件性能非常重要，开发电极界面材料是实现高性能器件的有效方法。我们发展出溶液加工型石墨烯电极界面材料，包括氧化石墨烯体系和石墨烯量子点体系。利用溶液加工型石墨烯化学结构易修饰、性质易调控的特点，我们进行了系统研究，实现了溶液加工型石墨烯能级结构、导电率、成膜性等多方面性质的大幅度协同调控，提升了器件性能。

3. 单一高分子白光材料

白光高分子发光材料与器件在全色显示、背光源、照明领域巨大的应用前景。白光是混合光，需要发光光谱有效覆盖整个可见光区。普通有机/高分子发光材料的发光光谱半峰宽小，无法覆盖整个可见光区，无法实现白光发射。我们在国际上提出并实现了单一高分子的三基色同时发光并得到白光，解决了白光高分子材料与器件光谱稳定性的难题，为发展单一高分子白光材料和带动全色显示应用拓展出新方向。
