“…For comparison, the limit of determination under lamp excitation for the same Al‐MIL‐101/Na 2 S system was found to be only 100 μ m in DMSO (Figure S11), in the range of those previously reported for other azido‐MOF sensors …”

“…Our azido‐modified Al‐MIL‐101 is thus an efficient and robust sensor for sulfide in biologically relevant media, reaching the 100 n m detection limit under laser excitation. This result is a three order of magnitude sensitivity increase with respect to previously reported fluorescent azido‐MOF which detected tens to hundreds micromolar sulfide under lamp excitation . The limit of determination of our system (100 n m ) is also lower than that reported for the Ellman reagent (600 n m ), which is widely used for the detection of SH‐containing compounds produced by bacteria.…”

“…Since the sulfide sensing reaction relies on the modification of the linker, the linker‐based 565 nm PL band is anticipated to be a more effective channel with respect to the already reported 460 nm band to establish a correlation between intensity and sulfide‐induced amino‐linker concentration in the solid. Its sensitivity will indeed prove to be especially valuable for detection at very low values requiring high sensitivity (see below).…”

“…Among them, luminescent MOFs, whose properties are mainly driven by metal cations, represent attractive platforms for the design of optoelectronic devices and especially sensors, offering an appealing opportunity for the detection of analytes in solution. Among recent examples, azido‐MOF (MOF‐N 3 ), based on Zr‐UiO‐66 and Zn‐IRMOF‐3 frameworks, have been reported for sulfide sensing in aqueous solution; the azido to amino reduction upon H 2 S exposure leads to turn‐on fluorescence under UV‐lamp excitation (see Scheme ) …”

Selective detection of H2S in the cellular systems using fluorescent CPs/MOFs is of great scientific interest due to their outstanding aqueous stability, biocompatibility and real‐time detection ability. Fabrication of such materials using complete biologically essential elements and applying them as an efficient biosensor is still quite challenging. In this context, two newly synthesized CPs containing biologically essential metal ion (Zn) and nitro/azido functional groups into the framework to sense extracellular and intracellular H2S by reducing into respective amines are presented. The CP‐1 containing the azide group acted as an efficient fluorescent turn‐on probe with the lowest detection limit (7.2 μM) and shortest response time (30 s) among the Zn‐based probes reported till date. Moreover, CP‐1 exhibited green luminescence in live cells after imaging a very low concentration of H2S, whereas the nitro analogue CP‐2 could not detect the target analyte due to its framework disruption.
