However, conventional aging assessment depends on the indirect detection of gaseous byproducts such as NO and NO\n                    <jats:sub>2<\/jats:sub>\n                    , which suffers from inherent signal hysteresis and environmental interference. To overcome these limitations, a ratiometric fluorescent sensing platform based on 7\u2010hydroxycoumarin (7\u2010HC) was developed for the direct and specific detection of\n                    <jats:italic>N<\/jats:italic>\n                    \u2010methyl\u2010p\u2010nitroaniline (p\u2010MNA). The presence of p\u2010MNA triggers effective fluorescence quenching of 7\u2010HC based on the inner filter effect with dual emission peaks at 373 and 445\u2009nm, and the ratiometric sensing strategy efficiently eliminates complex matrix disturbances and instrumental errors, significantly improving detection accuracy and anti\u2010interference capability. Experimental results show that the 7\u2010HC probe exhibits a rapid response within 20\u2009s and excellent selectivity toward p\u2010MNA against various common interferents. Furthermore, 7\u2010HC\u2010doped KBr pellets enable solid\u2010state visual detection of p\u2010MNA. Notably, the proposed strategy can distinguish propellant samples with different aging degrees at both solution and film levels. This work establishes a method for direct p\u2010MNA detection in propellants, providing a promising technical route for aging state evaluation and safety monitoring of energetic materials.\n                  <\/jats:p>","DOI":"10.1002\/bio.70647","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T04:46:43Z","timestamp":1791521203000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Coumarin\u2010Based Fluorescent Probe for the Detection of\n                    <i>N<\/i>\n                    \u2010methyl\u2010p\u2010nitroaniline in Propellant Aging"],"prefix":"10.1002","volume":"41","author":[{"given":"Yuanyu","family":"Tang","sequence":"first","affiliation":[{"name":"College of Chemistry and Chemical Engineering Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tingting","family":"Lei","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaona","family":"Li","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Chemical Power Hubei Institute of Aerospace Chemotechnology  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengyuan","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Chemical Power Hubei Institute of Aerospace Chemotechnology  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4250-5034","authenticated-orcid":false,"given":"Chaoyi","family":"Yao","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengtao","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Chemical Power Hubei Institute of Aerospace Chemotechnology  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuhui","family":"Chi","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Chemical Power Hubei Institute of Aerospace Chemotechnology  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9492-2115","authenticated-orcid":false,"given":"Minhuan","family":"Lan","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering Central South University  Changsha Hunan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.heliyon.2024.e39631"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1088\/1742-6596\/909\/1\/012077"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dt.2022.06.001"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/prep.200500026"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2016.12.049"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/prep.201800340"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/07370659708216071"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/prep.201500196"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/cem.3632"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2021.123039"},{"key":"e_1_2_10_12_1","doi-asserted-by":"crossref","unstructured":"C.McKeever E.Murphy A.Camisasca S.Giordani andE.Dempsey \u201cCarbon Nano\u2010Onion Modified Electrodes for Voltammetric Detection of Propellent Stabiliser 1 3\u2010Diethyl\u20101 3\u2010Diphenly Urea (Centralite) \u201d ECS Meet.
