Anovel fluorescence/colorimetric dual-mode detection strategy for uranium ions (UO(2)(2+)) is presentedbased on a cerium-sulfonyl calix[4]arene (SC4A) platform. The exo- and endo-rim sites of SC4A can coordinate with Ce(3+) and Ce(4+) ions, respectively, quenching Ce(3+) fluorescence and influencing the oxidase-like activity of Ce(4+). In the absence of UO(2)(2+), the solution of 3,3,5,5-tetramethylbenzidine (TMB) remains blue, but upon UO(2)(2+) binding, Ce(3+) dissociates from SC4A, restoring fluorescence, while UO(2)(2+) interacts with oxTMB, turning the solution from blue to colorless.
