It is not frequent to observe coupling between these two excited\u2010state processes. In this work, we have shown the coupling between excimer formation and ESIPT processes in a custom\u2010designed fluorophore (\n                    <jats:italic>E<\/jats:italic>\n                    )\u20102\u2010((naphthalen\u20101\u2010ylimino)methyl)\u20104\u2010nitrophenol (\n                    <jats:bold>NMNP<\/jats:bold>\n                    ) in different matrices using steady state and time\u2010resolved fluorescence spectroscopic measurements followed by quantum chemical calculations. Extensive spectral analyses of\n                    <jats:bold>NMNP<\/jats:bold>\n                    in different media reveal the occurrence of pre\u2010equilibrium excited\u2010state intramolecular proton transfer (ESIPT) between the enol form or normal form (N*) and tautomeric form or keto form (T*), where excimer (E*) formation is facilitated by delayed population decay and well\u2010ordered lattice packing, resulting in triple emissions of N* (400\u2013450\u00a0nm), T* (520\u2013550\u00a0nm), and E* (below 450\u00a0nm) with lifetime values 0.12\u20130.50\u00a0ns, 1.80\u20132.50\u00a0ns and &gt;5.0\u00a0ns, respectively. Theoretical potential energy curves (PECs) along the proton transfer coordinates using density functional theory (DFT) and time\u2010dependent density functional theory (TDDFT) suggest a low energy barrier for the excited state proton transfer process.\n                  <\/jats:p>","DOI":"10.1002\/asia.70843","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T04:02:52Z","timestamp":1781841772000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploration of Spectrodynamic Behavior of a Naphthalene\u2010Based Schiff Base (\n                    <i>E<\/i>\n                    )\u20102\u2010((Naphthalen\u20101\u2010ylimino)methyl)\u20104\u2010nitrophenol: Synergistic Effects of ESIPT and Excimers"],"prefix":"10.1002","volume":"21","author":[{"given":"Akash","family":"Das","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Calcutta  Kolkata India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7576-6930","authenticated-orcid":false,"given":"Nikhil","family":"Guchhait","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Calcutta  Kolkata India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8CS00185E"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajoc.202400572"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/agt2.160"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/asia.202101219"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsomega.0c02589"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsomega.3c09822"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7TC04207H"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0NJ05600F"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dyepig.2021.109488"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5CP00577A"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/jp035855n"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/s42004\u2010019\u20100113\u20108"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1039\/D5CP03573B"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jphotochem.2026.117055"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s44442\u2010026\u201000067\u20109"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1039\/D3CP05837A"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1351\/pac199668122223"},{"key":"e_1_2_10_19_1","volume-title":"Modern Molecular Photochemistry of Organic Molecules","author":"Turro N.
