Herein, the ultramicroporous Zn(II)\u2010based metal\u2010organic framework, MFM\u2010520, has been investigated for the adsorption and luminescent detection of H\n                    <jats:sub>2<\/jats:sub>\n                    S. Breakthrough measurements at 298 K and 1\u00a0bar show a reversible H\n                    <jats:sub>2<\/jats:sub>\n                    S uptake of 3.91\u00a0mmol g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , while powder X\u2010ray diffraction confirms full retention of crystallinity after adsorption. Solid\u2010state photoluminescence experiments reveal a pronounced, selective fluorescence turn\u2010off response to H\n                    <jats:sub>2<\/jats:sub>\n                    S in the gas phase, with a limit of detection of 6.13\u00a0ppm. Time\u2010resolved spectroscopy shows a decrease in the excited\u2010state lifetime upon H\n                    <jats:sub>2<\/jats:sub>\n                    S adsorption, indicating enhanced non\u2010radiative decay pathways. In situ DRIFTS measurements indicate that H\n                    <jats:sub>2<\/jats:sub>\n                    S interacts with MFM\u2010520 through supramolecular interactions. The combined adsorption, structural, and spectroscopic analyses establish that fluorescence quenching arises from reversible, confinement\u2010amplified modulation of ligand\u2010centered excited\u2010state dynamics. These results highlight how coordinatively saturated Zn(II) nodes within ultramicroporous environments can couple chemical stability with selective luminescent gas sensing.\n                  <\/jats:p>","DOI":"10.1002\/smll.74030","type":"journal-article","created":{"date-parts":[[2026,6,2]],"date-time":"2026-06-02T10:05:21Z","timestamp":1780394721000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mechanistic Insight into H\n                    <sub>2<\/sub>\n                    S\u2010Induced Fluorescence Quenching in a Robust Metal\u2013Organic Framework"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8274-2432","authenticated-orcid":false,"given":"Valeria B.","family":"L\u00f3pez\u2010Cervantes","sequence":"first","affiliation":[{"name":"Laboratorio de Fisicoqu\u00edmica y Reactividad De Superficies (LaFReS) Instituto De Investigaciones en Materiales Universidad Nacional Aut\u00f3noma De M\u00e9xico  Ciudad de M\u00e9xico M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan L.","family":"Obeso","sequence":"additional","affiliation":[{"name":"College of Chemistry and Molecular Engineering Beijing National Laboratory For Molecular Sciences Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
