A self-assembled metal–organic framework for enhanced UO22+ fluorescence sensing: integration of an octa-nuclear zinc cluster with hexakis(4-carboxyphenoxy)cyclotriphosphazene

A novel photoactive Zn-MOF was successfully synthesised by introducing a flexible cyclotriphosphonitrile hexacarboxylic acid, which achieves a sensitive fluorescence quenching response to radioactive UO 2 2+ ions and the heavy metal Fe 3+ .
