英文摘要: This project aims at preparing chiral carbonaceous nanotubes and mesoporous carbonaceous nanomaterials through a supramolecular templating method, and studying the exteral surface and internal chirality of organic self-assemblies and the origin of optical activity of carbonaceous nanomaterials. Firstly, a series of amino acid derivatives will be synthesized. Their self-assembly behavior will be controlled by tuning the kinds of amino acids and the lengthes of the alkyl chains. The structures and chirality of the supramolecular self-assemblies will be investigated using infrared spectroscopy, ultraviolet spectroscopy, X-ray diffraction, circular dichroism and diffuse reflectance circular dichroism (DRCD). Secondly, chiral carbon nanotubes and mesoporous carbon nanomaterials will be synthesized using a supramolecular-templating method. The chiral structures of the obtained carbonaceous nanomaterials will be controlled by adjusting the reaction conditions and the molecular structures of the supramolecular self-assemblies. Meanwhile, the origin of the optical activity of the carbonaceous nanotubes and mesoporous carbonaceous nanomaterials will be studied using DRCD, scanning and transmission electron microscopies. Finally, the obtained chiral carbon nanomaterials will be applied in the fields of enantioseparation,electromagnetic wave absorbtion and supercapacitor.
