Abstract

Abstract : We report a series of calix[ n ]triazoliums showing excellent selectivity for AMP. The unique supramolecular ensemble exhibits a selective turn-on fluorescence response towards AMP over various anions, including adenosine polyphosphates. Abstract : A novel calix[ n ]triazolium was synthesized and exhibited excellent selectivity for AMP. The binding between calix[ n ]triazolium and chromenolate anions forms a non-fluorescent complex and the resulting supramolecular ensemble selectively detects AMP in water and induces "turn-on" fluorescence. The sensing platform is the first macrocyclic system to discriminate AMP from ADP and ATP through fluorescence changes.
