Dopamine (DA) is a neurotransmitter with biologically important properties that play an important role in the function of the central nervous and cardiovascular systems. Abnormal DA concentrations in human biological fluids are thought to be associated with many neurological disorders. Luminescence have now become an effective method for the detection of DA. Ratiometric luminescent sensors with self-calibration exhibit higher sensitivity and selectivity than conventional single-emission sensors. In addition, Ln-MOFs sensors constructed based on lanthanide ions doping have the significant advantages of simple synthesis, green, and high stability. In this study, Eu
