吲哚区域选择性硅（硼）烷化反应在聚合物合成中的应用

Polymeric materials have been widely used in every aspects in our daily life due to their superior performance. However, their functional diversification were limited by both conventional polymer synthetic technologies and monomer structures. Therefore, it is very important to develop new elementary reactions and explore new type monomers for the synthesis of polymers with special properties. In this project, we successfully applied our new method for the preparation of C3-regioselective silylated or borylated indoles through B(C6F5)3-catalyzed (convergent) disproportionation reaction of indoles to the synthesis of polymeric materials with unique photoelectric properties, through using both indoles and hydrosilane or boranes as new type monomers. The topologies of such polymeric materials could be regulated by modifying the structures of monomers and a variety of polymeric material with different topologies have been successfully prepared for the investigation of the correlation between topologies and properties, including one, two and three-dimensional polymeric materials. Moreover, by tuning the substituents of monomers to change the photoelectric property of such polymeric materials would enable us to achieve a high-performance photoelectric polymer material.

高分子材料由于其优越的性能已经被广泛应用于我们日常生活的方方面面。由于传统的聚合物合成方法以及单体结构的单一性限制了聚合物功能多样性的发展，因此开发新的基元反应以及探索新型单体是赋予聚合物特殊性能的有效方法。本项目中我们通过使用吲哚以及硅（硼）烷作为新型的单体，将自主开发的B(C6F5)3催化的归一化歧化反应制备高选择性的3-位硅（硼）烷吲哚的方法应用于具有光电特性的高分子材料的合成。同时通过改变单体的结构实现调控聚合物的拓扑结构，合成出具有一维线性、二维平面和三维立体结构的聚合物材料，并考察聚合物的结构对聚合物性能的影响；此外，通过优化单体的取代基，可以实现对聚合物光电性能的进一步调控，以期最终得到高性能光电聚合物材料。
