Hydrogen Sulfide Sensing In their Communication on page 7002 ff. , M. Licchelli, R. Martínez‐Máñez, et al. report the synthesis, characterization, and sensing behavior of a new hybrid material functionalized with a Cu II ‐macrocyclic derivative that is capped, through electrostatic interactions, with the bulky anion hexametaphosphate. Of all the chemicals tested, only HS − was able to induce pore opening and dye release. The fluorogenic response obtained was ascribed to a demetallation reaction, selectively induced by HS − ion.
