A Self-Assembled Metal-Organic Framework for Enhanced UO22+ Fluorescent Sensing: Integration of 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+ .
