The developed probe possesses push\u2010pull architecture with 2\u2010(piperidyn\u20101\u2010yl) thiophene as the donor,\n                    <jats:italic>N<\/jats:italic>\n                    ,\n                    <jats:italic>N\u2019<\/jats:italic>\n                    \u2010dibutylbarbituric as the acceptor, and butadiene as the spacer. In contrast to weak solvatochromic behavior in organic solvents, the probe showed distinct optical photophysical properties in water resulting from the formation of nanoscopic aggregates. The probe underwent pronounced spectral changes upon the addition of hydrazine including an 11.5\u2010fold decrease in absorbance and ~2.4\u2010fold fluorescence quenching. The mechanistic investigation revealed the rapid formation of hydrazone upon the interaction of the probe with hydrazine via retro\u2010Knoevenagel reaction as confirmed experimentally and corroborated with DFT calculations. The induced colorimetric and fluorometric changes were utilized in hydrazine sensing with excellent selectivity over other biologically relevant analytes with a detection limit of 0.76\u2005\u03bcM in aqueous media. The practical utility of the probe was assessed in real\u2010life natural water samples, while we have also developed a cost\u2010effective portable kit for the on\u2010site hydrazine detection both in the solution and vapor phases.\n                  <\/jats:p>","DOI":"10.1002\/cplu.202400492","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T16:14:37Z","timestamp":1727280877000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Towards Portable Kits for On\u2010Site Colorimetric Detection of Aqueous Hydrazine Using Piperidine\u2010Thiophene\u2010Barbituric Acid Push\u2010Pull Probe"],"prefix":"10.1002","volume":"90","author":[{"given":"Rikitha S","family":"Fernandes","sequence":"first","affiliation":[{"name":"Department of Chemistry Birla Institute of Technology and Science Pilani Hyderabad Campus  Hyderabad 500078 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suvendu","family":"Paul","sequence":"additional","affiliation":[{"name":"Department of Chemistry Birla Institute of Technology and Science Pilani Hyderabad Campus  Hyderabad 500078 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milan","family":"Klikar","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Technology, Faculty of Chemical Technology University of Pardubice, Studentsk\u00e1 573  Pardubice 53210 Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Filip","family":"Bure\u0161","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Technology, Faculty of Chemical Technology University of Pardubice, Studentsk\u00e1 573  Pardubice 53210 Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3988-1509","authenticated-orcid":false,"given":"Nilanjan","family":"Dey","sequence":"additional","affiliation":[{"name":"Department of Chemistry Birla Institute of Technology and Science Pilani Hyderabad Campus  Hyderabad 500078 India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,11,27]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7AY02866K"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4RA11264D"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejoc.201700070"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/C9AN02058F"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.snb.2020.128450"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.microc.2020.105461"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.iecr.3c01754"},{"key":"e_1_2_6_8_1","author":"Fernandes R.
