Abstract: Copper ions are a significant concern to people's health and wine quality. By adopting a "one-pot" approach, tetra(4-carboxyphenyl)porphyrin (TCPP) molecules were integrated into UiO-66-NH2 metal–organic frameworks, forming TCPP@UiO-66-NH2 dual-emission fluorescence sensing platform towards copper ions. The blue fluorescence of UiO-66-NH2 at 466 nm was deemed an internal reference signal; thus, the built-in corrections in the complex were effectively achieved. The red emission fluorescence of TCPP at 654 nm was quenched by Cu2+, resulting in a reliable signal and noticeable color changes. A quick and sensitive ratio fluorescence sensor was constructed with the signal contrast mechanism. This sensor enabled trace detection of Cu2+ within the concentration range of 0–10 nM, with a detection limit as low as 24 nM, and exhibited good anti-interference capability and cycling stability. Further spiking-recovery experiments demonstrated excellent detection performance and analytical reliability of the sensor in water and red wine samples. [ABSTRACT FROM AUTHOR]
