寡聚芳酰胺是一类以芳环为构筑单元、酰胺键链接的稳定化合物,因含有氢的供体和受体使它对客体分子表现出特殊的识别能力,目前已成为国内外研究的热点领域之一。结合近年来国内外相关文献,首先综述了寡聚芳酰胺受体高效识别有机分子的研究进展,目前认为它主要通过氢键来识别醇类、胺类以及糖类等客体分子,并可通过修饰受体分子来提高选择性识别客体的能力;其次介绍了该受体识别无机分子的研究现状,当前研究较多客体分子包括富勒烯、水分子、肼、双氧水等,π-π共轭和氢键是该受体主要识别作用力;然后分别综述了该类受体分子在识别阳离子和阴离子方面的进展,前者包括有机阳离子、碱金属以及过渡金属,识别它们的主要作用力有配位键和氢键,后者包括无机阴离子和有机阴离子,识别它们的是电荷中性偶极作用力。然而,该类受体在制备和识别环境方面存在着不足,制备功能特定、性能稳定的寡聚芳酰胺受体分子是未来发展方向。
Oligomeric aromatic amides are a class of stable compounds with aromatic rings as building blocks and amide linkages. Since they contain hydrogen donors and acceptors, they have shown special recognition ability for guest molecules and have become a hot research field at home and abroad One of the fields. In this paper, we firstly reviewed the research progress on the recognition of organic molecules by oligomeric aromatic amide receptors. At present, it is mainly based on hydrogen bonds to recognize guest molecules such as alcohols, amines and carbohydrates, Receptor molecules to improve the ability of selective recognition of the object; secondly, the current research status of the recognition of inorganic molecules by this receptor is introduced. At present, more guest molecules include fullerene, water molecules, hydrazine, hydrogen peroxide, π- Hydrogen bond is the main recognition force of this receptor. Then, the progress of this kind of receptor molecule in recognizing cation and anion are summarized respectively. The former includes organic cation, alkali metal and transition metal. The main force recognizing them is coordinate bond And hydrogen bonds, the latter including inorganic anions and organic anions, and those that recognize them are charge-neutral dipole forces. However, there are deficiencies in the preparation and identification of this kind of receptors. It is the future direction for the preparation of oligoaramide receptor molecules with specific function and stable performance.
