Development of a fluorescence sensor using Na[Eu(TFNB)4] complex immobilized on anion-exchange resin for improved stability. Structural and photoluminescence analyses confirmed synthesis and stable red fluorescence at 612 nm. Exhibition of a concentration-dependent turn-off response to uric acid, with complete quenching at 350 μM and a visible red-to-blue color change at 420 μM.
