摘　　要：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。Aromatic oligoamide compounds are a class of aromatic ring as building units,the link of amide bond stable compounds,due to exhibiting special recognition ability to guest molecules by containing hydrogen donor and receptor,now they has become one of hot research fields in the world.In this review,according to the related papers at home and abroad in recent years,firstly we summarized the recent progress in molecular recognition of aromatic oligoamide compounds as synthetic receptors to organic molecules,the viewpoint that the guests molecules containing alcohol,amine and sugar were recognized by hydrogen bonding was accepted at present,and the selectivity recognition ability can be enhanced by modified receptors.Secondly,their current situation in molecular recognition to inorganic molecules was introduced,fullerene,water molecule,hydrazinium,hydrogen peroxide as guest molecules were researched frequently,which were recognized byπ-πinteraction and hydrogen bonding.Next,the recent progress of the receptors in molecular recognition to cation and anion were summarized,the former mainly contained organic cation,alkali metal and transition metal,which were recognized by coordination and hydrogen bonding.The latter contained inorganic anion and organic anion,which were recognized by charge-neutral dipoles.However,this kind of receptor molecules existing the shortcomings in synthesis and recognition condition fields were mentioned,and the receptors with given function and well stability will develop trends in the future.
