A water-stable lanthanide-organic framework as a recyclable luminescent probe for detecting pollutant phosphorus anions

Abstract

A novel 3D Eu-BTB framework (1) containing three types of 1D channels was synthesized and structurally characterized. Compound 1 exhibits high thermostability and water stability with the pH range from 2 to 12. Additionally, the luminescence explorations revealed that 1 can sensitively and selectively detect pollutant PO₄³⁻ among various colourless anions. More importantly, 1 represents the first example of regenerable MOF-based luminescent probes for detecting PO₄³⁻.
