The sensing properties towards aliphatic α,ω-dicarboxylates of five cyclohexane-based ligands are described. The studied ligands have been designed following the binding site-signalling unit approach and they all possess thiourea groups as recognition moieties. Ligands 1 and 3 containing naphthalene units can be used as fluorescent sensors as they form intra- or intermolecular excimers in the presence
描述了五种基于环己烷的配体对脂族α,ω-二羧酸酯的传感特性。所研究的配体是按照结合位点信号单元方法设计的,它们都具有硫脲基团作为识别基团。包含萘单元的配体1和3可以用作荧光传感器,因为它们在适当的二羧酸盐存在下形成分子内或分子间的受激准分子。已经观察到琥珀酸和丙二酸与其更长或更短的同源物的选择性感测。
