Pesticide binding and urea-induced controlled release applications with calixarene naphthalimide molecules by host-guest complexation. Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 53, 10, 669-676.0360-12341532-4109https://dx.doi.org/10.1080/03601234.2018.1474557https://hdl.handle.net/11492/2679WOS:000457090700004PubMed:29842827Three novel calix[4]arene molecule-based 1,8 naphthalimide fluoroionophore for the selective determination of kesoxim-methyl were synthesized and used in pesticide binding studies. The possible interaction between pesticides and fluorescent calix[4]arene molecules was monitored by UV/Vis absorption and fluorescence spectroscopy. When compared the studied pesticides, kesoxim-methyl was strongly quenched the fluorescence intensity of upper rim-modified calix[4]arene. UV and fluorescence titration experiments were also studied to determine both the quenching mechanism and stoichiometric ratio consisted in complex formation. Furthermore, pesticide release experiments were also performed with a fertilizing agent as urea by using fluorescence spectroscopy technique.enCalixarenePesticideControlled ReleaseHost-GuestKesoxim-MethylArticle5310669676info:eu-repo/semantics/closedAccess2-s2.0-85047809118WOS:0004570907000042984282710.1080/03601234.2018.1474557Q2Q3
