Abstract

The current study investigated host-guest complexation in 6-p-toluidinylnaphthalene-2-sulfonate (), a fluorescence probe used to investigate hydrophobic regions that contain the water-soluble cationic pillar[6]arene (). After complexation with , the fluorescence intensity of was significantly increased. The decreases in the fluorescence intensity of the • complex when phenolic food-additives are added have been used in indicator displacement assays to detect food additives in the water.

摘要

当前的研究调查了6-对甲苯胺基萘-2-磺酸盐（一种用于研究含有水溶性阳离子柱[6]芳烃的疏水区域的荧光探针）中的主客体络合作用。与[6]芳烃络合后，[6]芳烃的荧光强度显著增加。当加入酚类食品添加剂时，[6]芳烃与[6]芳烃络合物的荧光强度降低，这已被用于指示剂置换分析以检测水中的食品添加剂。
