An easy assembled fluorescent sensor for dicarboxylates and acidic amino acids

Abstract

Two mesitylene based neutral receptors 1 and 2 bearing two thiourea binding sites were constructed as fluorescent probes for sensing dicarboxylates. Their binding affinities toward dicarboxylates, aspartate and glutamate have been investigated in acetoni-trile solution by fluorescence titration experiments. Both fluorescent sensors exhibited some ability to discriminate the antipodal forms of aspartate and glutamate. © 2011 Zhou et al; licensee Beilstein-Institut.
