A supramolecular optic sensor for selective recognition AMP

Cu-coordinated complex based on 7-membered amide cycle has been designed and synthesized. And its binding ability with nucleotides (AMP, adenosine 5′-monophosphate; ADP, adenosine 5′-diphosphate; ATP, adenosine 5′-triphosphate) has been studied by UV–vis spectrum. Results indicate that the receptor shows the highest binding ability with AMP among studied nucleotides and can selectively and strongly bind nucleotides at neutral medium. The receptor can be used as optical sensor for the detection of AMP.
