A new receptor based on a 9,9-dimethylxanthene framework was synthesized. Owing to its suitable oxyanion hole structure, this receptor is able to associate carboxylic acids and anions. The introduction of a chiral center provides enantioselective properties to this receptor as a result of its different interactions with both enantiomers of the substrate. The combination of this skeleton with a fluorescent
合成了一种基于 9,9-二甲基呫吨骨架的新受体。由于其合适的氧阴离子孔结构,该受体能够结合羧酸和阴离子。由于其与底物的两种对映异构体的不同相互作用,手性中心的引入为该受体提供了对映选择性特性。该骨架与丹磺酰基等荧光单元的组合允许利用荧光技术检测少量羧酸。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
