Dual-functional Porphyrinic Zirconium-based Metal-Organic Frameworks for Fluorescent Sensing of Histidine Enantiomers and Hg2+

A novel fluorescence sensor based on porphyrinic zirconium-based metal-organic frameworks, L-cysteine modified PCN-222 (L-Cys/PCN-222), was developed to selectively recognize histidine enantiomers and sensitively detect Hg2+. The dual-functional sensor was successfully...
