Sequential and recyclable sensing of Fe³⁺ and ascorbic acid in water with a terbium(<scp>iii</scp>)-based metal–organic framework

Abstract

, accompanied by the near-entire recovery of MOF 1 emission. The density functional theory (DFT) calculation results support the proposed mechanism. Such a sensing cycle is further transferable to urine and serum samples with a satisfactory near-quantitative recovery, highlighting its good potential in biologically relevant applications.
