Abstract

Abstract : The role of the organic building units of MOFs towards selective detection of a targeted metal cation (Fe 3+ ) has been demonstrated by systematic screening by varying the number of Lewis basic (pyridyl‐N atoms) sites in a series of isostructural metal–organic frameworks (MOFs). All three fluorescent MOFs are seen to present a quenching response towards Fe 3+ ions in water; however, only UiO‐67@N exhibits highly selective and sensitive response, whereas the emission of both UiO‐67 and UiO‐67@NN is quenched by several metal ions. More information can be found in the Research Article by S. K. Ghosh et al. (DOI: 10.1002/chem.202104175 ).
