有机π功能分子的创制与性能研究

有机π分子是有机化学的重要组成部分。基于有机π分子独特的分子结构与电子云分布,有机π分子呈现出特有的光、电、磁等特性,在功能材料领域具有重要应用。我们课题组的研究兴趣主要集中于两个方面:

Ø 有机π分子(包括有机小分子和聚合物)的创制与物理化学性质研究

以功能为导向,开展新型有机π分子的创制研究,主要集中于具有独特光、电性能的有机π功能分子(如稠环化合物,非稠环小分子和共轭聚合物),研究其光吸收、光发射和氧化还原性质,自组装行为。

Ø 有机光电器件的构筑与表征

本研究方向主要是利用本实验室合成的有机π分子构筑光电器件(包括薄膜器件和微纳器件),优化器件构筑工艺,测试器件性能,探索分子在有机光电子学方面的应用,并对有机π分子结构与性能的关系和实验中出现的独特现象进行深入研究。


Research Intersts:

π-functional materials and applications (especially for transistors and solar cells).

We mainly focus on : (1) the design and syntheses of conjugated small molecular organic semiconductors (including fused ring compounds and oligomers) and polymer semiconductors, (2) investigating the aggregation behaviors of organic semiconductors and their properties in aggregation states, (3)fabricating transistors and bulk heterojunction solar cells.
