Herein, we report the development of a water\u2010soluble, naphthalimide\u2010based fluorescent polymeric probe,\n                    <jats:bold>DCP\u20101<\/jats:bold>\n                    , for the selective and rapid sensing of FA in aqueous solutions at physiological pH. The polymer has aromatic amine functional groups in its side chains, which specifically react with FA to form a stable imine. This transformation inhibits the native photoinduced electron transfer (PET), resulting in a distinct \u201cturn\u2010on\u201d fluorescence response in an aqueous medium. The generation of the imine adduct was confirmed by mass spectrometry (MS) and\n                    <jats:sup>1<\/jats:sup>\n                    H NMR spectroscopy for the representative reaction between a small molecule analogue and FA.\n                    <jats:bold>DCP\u20101<\/jats:bold>\n                    exhibits excellent sensitivity, detecting FA at concentrations as low as 1.28\u00a0nM and displaying a strong fluorescence response within minutes at 100\u00a0nM FA. The probe exhibited reversible behavior upon bisulfite addition, demonstrating its ability to be reused efficiently for multiple FA detection cycles with consistent performance. Density functional theory (DFT) calculations further validated the proposed PET\u2010based sensing mechanism.\n                  <\/jats:p>","DOI":"10.1002\/asia.70954","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T10:22:58Z","timestamp":1787048578000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Macromolecular Fluorimetric Probe With Naphthalimide Pendants for Selective Formaldehyde Detection"],"prefix":"10.1002","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0549-2097","authenticated-orcid":false,"given":"Swagata","family":"Pan","sequence":"first","affiliation":[{"name":"Polymer Research Centre and Centre for Advanced Functional Materials, Mohanpur  Nadia West Bengal India"},{"name":"Department of Chemical Sciences Indian Institute of Science Education and Research Kolkata  Nadia West Bengal India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9520-835X","authenticated-orcid":false,"given":"Subhadip","family":"Roy","sequence":"additional","affiliation":[{"name":"Polymer Research Centre and Centre for Advanced Functional Materials, Mohanpur  Nadia West Bengal India"},{"name":"Department of Chemical Sciences Indian Institute of Science Education and Research Kolkata  Nadia West Bengal India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satendra","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Chemical Sciences Indian Institute of Science Education and Research Kolkata  Nadia West Bengal India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5486-3395","authenticated-orcid":false,"given":"Priyadarsi","family":"De","sequence":"additional","affiliation":[{"name":"Polymer Research Centre and Centre for Advanced Functional Materials, Mohanpur  Nadia West Bengal India"},{"name":"Department of Chemical Sciences Indian Institute of Science Education and Research Kolkata  Nadia West Bengal India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr800399g"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cotox.2018.07.001"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/d1cc05644a"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcmm.16602"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11357\u2010012\u20109388\u20108"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mrrev.2008.07.002"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2016.00257"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/chromsci\/46.6.461"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00128\u2010007\u20109172\u20100"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1006\/abio.2002.5682"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12273\u2010024\u20101172\u2010z"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jphotochem.2020.112701"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2023.215338"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/macp.202400434"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1080\/14686996.2021.2018920"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1080\/10601325.2024.2303360"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/asia.202401053"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1080\/10601325.2024.2333899"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1080\/14686996.2024.2423597"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eurpolymj.2024.113241"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsapm.5c01099"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1080\/10601325.2024.2328733"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1021\/acssensors.8b00835"},{"key":"e_1_2_8_25_1","doi-asserted-by":"publisher","DOI":"10.1080\/14686996.2025.2469493"},{"key":"e_1_2_8_26_1","doi-asserted-by":"publisher","DOI":"10.1002\/asia.202500676"},{"key":"e_1_2_8_27_1","doi-asserted-by":"publisher","DOI":"10.1080\/10601325.2025.2555914"},{"key":"e_1_2_8_28_1","doi-asserted-by":"publisher","DOI":"10.1021\/ma020362m"},{"key":"e_1_2_8_29_1","volume-title":"Vogel's Textbook of Practical Organic Chemistry","author":"Furniss B.
