The ligand 3\u2010ally\u2010salicylohydrazide (S<jats:sub>1<\/jats:sub>) was synthesized, then was confirmed by IR, CHN, LC\u2013MS and <jats:sup>1<\/jats:sup>H NMR. The sensitivity of the probe's fluorescence spectra towards the presence of eight organophosphorus pesticides in ethanolic solution was studied, in which the probe showed marked sensitivity towards dichlorvos pesticide. A tangible enhancement of the probe's fluorescence intensity was observed as a consequence of the gradual addition of dichlorvos pesticide. The calculated limit of detection (LOD) was 1.183\u00a0\u03bcM and limit of quantitation (LOQ) was 3.94\u00a0\u03bcM. Further characterization of the nature of forces acting in the interaction of the probe with dichlorvos was performed by calculation of binding constants at different temperatures according to the Benesi\u00a0\u2212\u00a0Hildebrand equation, and the thermodynamic parameters \u0394H, \u0394S and \u0394G. In order to assess the analytical applicability of the method, the influence of various potentially interfering anion and cations that naturally occur in water and soil were calculated.<\/jats:p>","DOI":"10.1002\/bio.3357","type":"journal-article","created":{"date-parts":[[2017,6,29]],"date-time":"2017-06-29T01:22:40Z","timestamp":1498699360000},"page":"1541-1546","source":"Crossref","is-referenced-by-count":17,"title":["Fluorescence sensing of dichlorvos pesticide by the luminescent Tb(III)\u20103\u2010ally\u2010salicylohydrazide probe"],"prefix":"10.1002","volume":"32","author":[{"given":"Ibrahim Ahmed","family":"Ibrahim","sequence":"first","affiliation":[{"name":"Chemistry Department, Faculty of Science Suez Canal University  Ismailia Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas Mamdoh","family":"Abbas","sequence":"additional","affiliation":[{"name":"Chemistry Department, Faculty of Science Suez Canal University  Ismailia Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9635-6436","authenticated-orcid":false,"given":"Hatem Medhat","family":"Darwish","sequence":"additional","affiliation":[{"name":"Chemistry Department, Faculty of Science Suez Canal University  Ismailia Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,6,29]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1574-6976.2006.00018.x"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.2136\/sssaspecpub22"},{"key":"e_1_2_7_4_1","series-title":"Irrig.
