Dual-functional porphyrinic zirconium-based metal–organic framework for the fluorescent sensing of histidine enantiomers and Hg²⁺

Abstract

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...
