Regulating the energy level of a lanthanide (III) metal–organic framework (Ln-MOF) via an "antenna effect" is effective strategy for achieving ratiometric luminescent dynamics carcinoid biomarker sensing application. Herein, we present europium-based MOF material {[Eu(BPDC)(μ3–OH)(H2O)2]·2.5H2O}n (Eu-MOF, H2BPDC = 2,2′-bipyridine-4,4′-dicarboxylic acid and DMF N,N-dimethylformamide), incorporating tetranuclear cubane-like [Eu4(μ3–OH)4(COO)4]4– cluster cores, 5-hydroxyindole-3-acetic (5-HIAA) detection through influence Eu3+ ions sensitized by ligands as well 5-HIAA. Luminescence titration experiments indicate Eu-MOF can demonstrate simultaneous luminescence emission signals cations 5-HIAA, resulting in on–off 5-HIAA response to concentrations demonstrating superior stability excellent performance such low limit (LOD 37.16 nM), high selectivity (Ksv 2.39 × 104 M–1), fast (≤1 min), attractive recyclability (≥five times). Derived from contribution competitive absorption coordination interactions between exhibits visually observable color change red purple naked eye illuminated ultraviolet light, confirmed fabrication portable hydrogels. More importantly, smartphone assistance based on RGB chromaticity analysis has been developed intelligent Eu-MOF@PVA Eu-MOF@PU films have proposed real-time visual thereby enhancing practical applicability quantitative trace
