Recently Ghosh et al. reported on the fluorescent response of commercially available N ‐(2‐aminoethyl)naphthalen‐1‐amine toward Fe II , Fe III , and Hg II (K. Ghosh, S. Rathi, P. Gupta, P. Vashisth, V. Pruthi, Eur. J. Inorg. Chem. 2015 , 311 ). The authors conclude that metal binding to the diamine chelator leads to chelation‐induced quenching; however, the experimental protocols are incompatible with the aqueous chemistry of Fe III , which precludes this interpretation of the data.
