Tobacco use in its various forms is the leading preventable cause of death, illness, and disability worldwide. Nicotine (NCT), a natural alkaloid found in tobacco plants, is a psychoactive substance and the primary component responsible for the addictive properties of such products. Since NCT is an analyte with low native fluorescence, the use of a fluorophore that interacts with it is necessary for its quantification by molecular fluorescence. This work describes, for the first time, a method to determine NCT based on the enhancement of fluorescence of the metal\u2013organic framework (MOF) europium terbium 2\u2010phenylsuccinate (Eu\u2010Tb\u2010PSA), at\n                    <jats:italic>\u03bb<\/jats:italic>\n                    <jats:sub>em<\/jats:sub>\n                    \u2009=\u2009611\u2009nm (\n                    <jats:italic>\u03bb<\/jats:italic>\n                    <jats:sub>exc<\/jats:sub>\n                    \u2009=\u2009280\u2009nm). The experimental variables that influence the quantification of NCT were studied and optimized.
