Europium(<scp>iii</scp>) β-diketone complex as portable luminescent chemosensor for naked eye Cu²⁺ detection and recyclable on–off–on vapor response

Abstract

A novel Eu³⁺ complex coordinated by polymers with β-diketone pendant groups (Eu³⁺–PDKMA) has been synthesized for Cu²⁺ cation and acid–base vapor detections.
