A new pyrazoline derivative 1-(2-hydroxyphenyl)-4-(9-anthryl)-3-benzothiazole pyrazolin (P1) was designed and synthesized. The recognition properties of the target compound P1 with metal ions had been investigated by UV absorption and fluorescence spectrophotometry. The probe exhibits several favorable features, including instantaneous, reversible recognition, high sensitivity and selectivity to copper ions. Cytotoxicity test and fluorescent immunoassay results show that compound P1 has good biocompatibility and low toxicity with its IC50 value of 376.558 μmol/L.
