these receptors can associate with carboxylic acids. The combination of this skeleton with a fluorescent unit such as dansyl allows the detection of small amounts of carboxylic acids by making use of fluorescent techniques, such that the response of daxabe depends on the nature of the guest. Anions such as halogenides are also suitable guests for daxabe and can be associated. This receptor also afforded
已经合成了一组基于二甲基呫吨骨架的新受体。由于其合适的氧阴离子孔结构,这些受体可以与羧酸结合。这种骨架与荧光单元(如丹磺酰)的组合允许通过使用荧光技术检测少量的羧酸,这样 daxabe 的响应取决于客体的性质。阴离子如卤化物也是 daxabe 的合适客体,可以缔合。在 18-crown-6 醚存在下,该受体在将两性离子氨基酸从水层提取到有机层方面也提供了良好的结果。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
