摘要

Stereoselective displacement of diacridylnaphthalene N,N'-dioxide ligands, 1, from a scandium(III) complex can be used for quantitative detection of 1,2-diaminocyclohexane isomers. The diastereoselective sensing assay with Sc(syn-1)(2) shows excellent linearity between the sample de and the measured UV absorption change, and sensing of mixtures comprising both low and high de values gave results within 5% accuracy. All three stereoisomers of 1,2-diaminocyclohexane can be differentiated using Sc[anti-(-)-1](2) in the same ligand displacement assay.
