The parent coordination polymer Ga(OH)(btec) ⋅ 0.5H 2 O(MIL‐61) was synthesized by the method of hydrothermal synthesis, and Eu 3+ was incorporated by the post‐synthesis modification method to obtain the coordination polymer Eu@MIL‐61 with excellent luminescence properties. Eu@MIL‐61 was developed as an excellent nano‐fluorescent probe for the detection of 2‐naphthol in urine. The study showed that Eu@MIL‐61 could selectively respond to 2‐naphthol, a biomarker of naphthol, with fluorescence quenching effect. More importantly, the probe has fast response time and low detection limit. In addition, the framework is not affected by the acid‐base properties of the solution and has good water stability and can be used to monitor the concentration of 2‐naphthol in urine.
