“…Similar phenomenon has been reported in other MOFs with uncoordinated carboxylate oxygen atoms. [30,31] Meanwhile, fluorescence lifetime of MOF-1 before and after sensing Fe 3 + and Cr 2 O 7 2À were also recorded. The reduced fluorescence lifetime in the present of Fe 3 + and Cr 2 O 7 2À confirmed dynamic quenching process (Figure S10).…”

In this work, NH2‐containing organic ligand 5‐Aminoisophthalic acid (AIPA), and trans‐1,2‐bis(4‐pyridyl)ethene (bpe) were selected as organic ligands to construct a new two‐dimensional luminescent Zn(II) metal‐organic framework [Zn(AIPA)(bpe)1/2]·named MOF‐1. It is worth noting that MOF‐1 exhibited excellent thermal stability and chemical stability in common solvents and different pH aqueous solution. As we expected, the luminescence sensing investigations demonstrated that MOF‐1 could be deemed as a multifunctional fluorescence sensor toward Cr2O72‐ and Fe3+ via a “turn‐off” effect.Notably, MOF‐1 had high selectivity and sensitivity for Fe3+ and Cr2O72‐ with low detection limits of 9.72× 10‐5 M and 1.95× 10‐5 M, respectively. Furthermore, the possible quenching mechanisms were also explored in detail.
