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

A novel 3D Eu-BTB framework () containing three types of 1D channels was synthesized and structurally characterized. Compound exhibits high thermostability and water stability with the pH range from 2 to 12. Additionally, the luminescence explorations revealed that can sensitively and selectively detect pollutant PO4(3-) among various colourless anions. More importantly, represents the first example of regenerable MOF-based luminescent probes for detecting PO4(3-).
