新型共价有机骨架材料:

共价有机骨架材料(COFs)是一类新型结晶性多孔聚合物,通过可逆反应自动而精确地把有机单元合并到周期性结构中,创造高度有序的π柱状阵列和一维开放通道。其具有大的比表面积及孔隙率、低的骨架密度、较高的化学稳定性及可控的孔道结构等优点,在气体或有机分子的吸附及分离、能量贮存、异相催化、传感、光电以及生物医药等众多性质。本课题组致力于通过分子结构设计,构筑具有新拓扑结构或者有官能团修饰的功能型COFs,并探索新型共价有机骨架材料在吸附分离、光电等领域的应用。同时,我们还关注COFs合成方法的领域,力求在更简单、更温和的条件下快速制备得到具有高结晶性的COFs

Research Interests

Covalent organic frameworks (COFs), an emerging class of crystalline porous materials, are constructed by incorporating organic building blocks into predetermined networks through strong covalent bonds based on reticular chemistry. Featuring unique high crystalline and porosity, low density, excellent stability and predictable periodic channel structure, COFs are promising materials for application in gas storage and separation, liquid phase adsorption, energy storage and conversion, heterogeneous catalysis, sensors and drug delivery. We currently focus on constructing novel COFs with sophisticated topologies or functional groups, and exploring their applications in adsorption, separation, optics, electrics, etc. Meanwhile, we are also seeking facile and rapid ways to prepare crystallized COFs under mild condition.

Carbon quantum dots are a new class of carbon nanomaterials that have emerged recently and have garnered much interest as potential competitors to conventional semiconductor quantum dots. We currently focus on the rational design and synthesis of high performance (high quantum yield, small full width at half maxima) carbon quantum dots from aromatic amines, together with the study of their multi-mode photoluminescence behaviors and relative applications.
