Ratiometric lanthanide coordination polymers (Ln-CPs) are advanced materials that combine the unique optical properties of ions (e.g., Eu3+, Tb3+, Ce3+) with structural flexibility and tunability polymers. These widely used in biological chemical sensing, environmental monitoring, medical diagnostics due to their narrow-band emission, long fluorescence lifetimes, excellent resistance photobleaching. This review focuses on composition, sensing mechanisms, applications ratiometric Ln-CPs. The mechanism relies two distinct emission bands, which provides a self-calibrating, reliable, precise method for detection. relative intensity ratio between these bands varies concentration target analyte, enabling real-time monitoring minimizing interference. approach is particularly suitable detecting trace analytes use complex environments where factors like background noise, temperature fluctuations, light variations may affect results. Finally, we outline future research directions improving design synthesis Ln-CPs, such as incorporating long-lifetime reference luminescent molecules, exploring near-infrared systems, developing up-conversion or two-photon materials. Progress areas could significantly broaden scope Ln-CP applications, especially biosensing, other fields.
