手性功能炭材料形成机理和结构设计研究

The structure designing and synthesis approaching of chiral functional carbon materials is a challenge topic in material and chemistry fileds due to its important theory and application value in chiral molecules separation, recognition and chiral catalysis reaction. The aim of this project tries to design morphology and control chiral pore structure of chiral porous carbon material. The forming mechanism of chiral carbon precursors will be illustrated, and the interaction between chiral molecules, chiral molecules with non-chiral molecules, polymer monomers will be investigated when chiral molecules or chiral structure materials are used as templates and nitrogen-containing molecules are selected as carbon sources. The effect of chiral template and carbon precursor on the structure and surface chemical property of chiral porous carbon will be elaborated in molecule level. Structure orientation, chiral transcription and heredity of chiral templates will be discussed during nitrogen-containing monomer polymerization and carbonization processes to obtain the mechanism of molecules state to chiral porous carbon material, which will provide theoretical recognization from molecular self-assembly to chiral porous carbon materials. The chiral structure keeping and heredity of chiral carbon precursor during carbonization process will be studied to realize the controllable synthesis and selective designing morphology between nitrogen-containing polymer and resultant porous carbon material. In addition, the application properties of chiral porous carbon material in molecule separation and chiral catalysis reaction performance will be investigated to reveal the relationship between structure and function of chiral porous carbon material.
