The investigation of N-phenyl-4-amino- and N-phenyl-4-acetamido-1,8-naphthalimides containing N-benzo-15-crown-5 ether substituent showed that the presence of ionophoric fragment as N-substituent in naphthalimide molecule provides the design of compound possessing the properties of fluorescent receptor. The addition of metal cations does not change the position of absorption and emission bands but substantial increases the fluorescence intensity. The study of molecules included the theoretical and experimental (optical, NMR) methods, analysis of intramolecular charge (electron) transfer and fluorescence properties in the presence and absence of metal ions.
研究了含有 N-苯并-15-冠-5 醚取代基的 N-苯基-4-氨基-和 N-苯基-4-乙酰胺基-1,8-萘酰亚胺，结果表明，萘酰亚胺分子中作为 N-取代基的离子载体片段为设计具有荧光受体性能的化合物提供了依据。金属阳离子的加入不会改变吸收和发射带的位置，但会显著增加荧光强度。这些分子的研究包括理论和实验（光学、NMR）方法、分子内电荷（电子）转移和有无金属离子存在时的荧光性质的分析。
