It showed fluorescent enhancement for Fe2+ ion by photoinduced electron transfer mechanism and fluorescence quenching for Cu2+ ion by charge-transfer process. Binding stoichiometry for [LH\u2013(Fe2+)2] and [LH\u2013(Cu2+)2] was found to be 1:2 by Job\u2019s plot method and, the binding constants were calculated as 1.6638 \u00d7 1010 and 9.22929 \u00d7 108 M\u20131, respectively. Compound LH exhibited OR and XOR logic gate behavior with H+, Fe2+, and Cu2+ as inputs. Further, the compound LH and bovine serum albumin binding interaction showed quenching of fluorescence by Fo\u0308rster resonance energy-transfer mechanism.<\/jats:p>","DOI":"10.1021\/acsomega.8b00748","type":"journal-article","created":{"date-parts":[[2018,7,18]],"date-time":"2018-07-18T23:24:12Z","timestamp":1531956252000},"page":"7985-7992","source":"Crossref","is-referenced-by-count":84,"title":["On\/Off Fluorescent Chemosensor for Selective Detection\nof Divalent Iron and Copper Ions: Molecular Logic Operation and Protein\nBinding"],"prefix":"10.1021","volume":"3","author":[{"given":"G.","family":"Tamil Selvan","sequence":"first","affiliation":[{"name":"Karunya Institute of Technology and Sciences , , , ,","place":["Coimbatore, Tamil Nadu, India, 641114"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chitra","family":"Varadaraju","sequence":"additional","affiliation":[{"name":"Karunya Institute of Technology and Sciences , , , ,","place":["Coimbatore, Tamil Nadu, India, 641114"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Tamil Selvan","sequence":"additional","affiliation":[{"name":"Karunya Institute of Technology and Sciences , , , ,","place":["Coimbatore, Tamil Nadu, India, 641114"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Israel V.
