“…[2,14,15] Boronic-acid-based fluorescence sensors for tartaric acid, [32] d-glucuronate, [33,34] and d-glucarate [35] have been reported, as has a boronic-acidbased colorimetric indicator-displacement assay for the determination of the enantiomeric excess of a-hydroxy acids. [36] Hydrogen-bonding receptors for the binding of tartaric acid [37] and the chiral discrimination of hydroxy carboxylates [38] and tartaric acid [39,40] are also known. In order to develop improved fluorescent chiral discriminating systems, we investigated the interaction of the two chiral forms of sensor 1 (R and S) with a range of sugar acids over a range of pH values.…”

“…To study the binding behaviour of receptor 1 towards the dicarboxylic acids, the 1 H NMR spectra of receptor 1 and a (1:1) complex with various diacids (malonic, succinic, glutaric, adipic, pimelic, suberic and 1,4-phenylenediacetic) are recorded in 1% DMSO-d 6 in CDCl 3 to make the solutions homogeneous. 1 The amide proton in 1 H NMR of the receptor 1 appearing at d ¼ 8.49 (Figure 3) ppm shows appreciable downfield chemical shifts (Dd ¼ 0.37 -0.67 ppm) of amide protons (Table 2) by all the seven dicarboxylic acids.…”

“…Receptors for neutral molecules are mainly designed based on the hydrogen bonding donor -acceptor array of the guest -host molecules. Among different functional groups, the amide group is mostly used (5,6) in the recognition of mono-and dicarboxylic acids owing to its presence in proteins. In this regard, pyridine amides have been widely used for carboxylic acid recognition.…”
