利用萘基席夫碱大环主客体超分子结构组装纳米带

Assembly of Nanoribbons Using Host-guest Supramolecular Structure of Naphthyl Schiff Base Macrocycle

合成具有明确形状和大小的一维纳米结构,如纳米纤维、纳米管和纳米带,在材料和生物研究领域中受到广泛关注。通过精确组织具有非共价相互作用的超分子结构,形成一维纳米结构是近年来超分子科学研究的重点。本文对萘基席夫碱大环与带有正电荷的十六烷基吡啶形成的超分子主客体结构进行研究,发现该主客体超分子结构可进一步自组装成纳米带,并对该纳米带进行了研究和表征。

The synthesis of one-dimensional nanostructures with definite shape and size,such as nanofibers,nanotubes and nanoribbons,has attracted wide attention in the fields of materials and biological research.In recent years,it is the focus of supramolecular science to form one-dimen-sional nanostructures by accurately organizing supramolecular structures with non-covalent interactions.In this paper,the supramolecular host-guest structure formed by naphthyl Schiff base macroring and cetylpyridine with positive charge was studied,and it was found that the host-guest supramo-lecular structure could be further self-assembled into nanoribbons,and the nanoribbons were studied and characterized.
