Nuclear accidents, uranium mining, and nuclear weapons production pose significant health and environmental concerns, and as a consequence there is ongoing interest in techniques for rapid and selective detection of the uranyl ion (UO 2 2+ ). In this study, a β-keto-enamine-linked covalent organic framework (COF) fluorescent probe was synthesized by a simple one-step condensation reaction using 1,3,5-triformylphoroglucinol (Tp) and 3,3′-dihydroxybenzidine (Db). Tp-Db exhibited a UO 2 2+ detection limit of 99.34 nM and a 10 s reaction time, ...
