The invention relates to a phenanthrene imidazole reversible fluorescence probe for Cu detection, and a preparation method and application thereof, relates to the fluorescence probe for the Cu detection, and the preparation method and the application thereof, and aims to solve the technical problems of an existing fluorescence molecular probe is poor in Cu detection reversibility and easy to be interfered by other metal ions. The reversible fluorescence probe provided by the invention has a structural formula as shown in the figure. The preparation method comprises the steps of (1) using phenanthrenequinone, o-nitrobenzaldehyde and ammonium acetate for synthesizing an intermediate compound I; (2) using the intermediate compound I, raney nickel, ethanol and hydrazine hydrate for synthesizing an intermediate compound II; (3) reacting the the intermediate compound II and salicylaldehyde, and obtaining the phenanthrene imidazole reversible fluorescence probe for the Cu detection. During detection, after the reversible fluorescence probe is acted with Cu, the fluorescence intensity is quenched; after Cr is added, the fluorescence intensity is recovered and can be used for detecting pollution of the Cu and the Cr in water.
