中文摘要： 随着多孔固体在储能、催化等领域的应用，对相关反应机理的研究和新性能的开发已成为多孔材料研究领域的热点和前沿问题。由于存在特殊的骨架和孔道结构，多孔固体中的电子转移行为有别于其他固体材料。本项目拟从多孔固体的设计合成出发，发展具有特定组成和结构的多孔固体的可控制备；围绕电子在多孔骨架、骨架与客体分子或骨架与骨架之间的转移机制进行深入研究，明确电子转移的驱动力、影响因素及状态；针对电子转移过程在有机小分子的催化转化、电化学及光电化学等功能体系中的机制与功效进行系统探索，建立电子转移机制与反应功效之间的关系。本项目对于开发新型多孔固体材料、从原子和分子水平认识多孔固体中电子转移过程与功效、促进多孔固体在催化和电化学与光电化学体系中的实际应用具有重要意义。

英文摘要： Porous solids with various structures, compositions and morphologies have been widely used as catalysts, photocatalysts, and energy-storing materials. Electron tranfer usually plays an important part in the processes of catalysis, energy storage and conversion. Owing to the unique features of the porous frameworks, the electron transfer in a porous solid is different from in other solid materails. The investigation of electron transfer is of particular significance for the elucidation of reaction machanism involving a porous solid. Thus, the understanding of electron transfer which facilitates the exploration of new functions of porous solids is highly desirable. In this project, new porous solids with particular structures and compositions will be designed and prepared through well selected synthetic strategies and control of the reaction conditions. The catalytic, photovoltaic, and electrochemical performance of the porous solids will be systematically evaluated. More importantly, the process of electron transfer within the framework of a porous solid, or from the framework of a porous solid to guest species will be investigated. The driving forces for the electron transfer processes will be clarified. The impact of electron transfer on the functions of porous solids will be carefully elucidated. The investigation performed in this project on the mechanism and functions of electron transfer involving porous solids is of foundmental and practical significance for the rational design and construction of novel functional porous solids.
