A novel imidazophenazine lactam fluorescence chemosensor (S1) was designed, synthesized and characterized by 1H NMR, 13C NMR and HRMS techniques. Fluorescence spectra of S1 in dimethyl sulfoxide (DMSO) solution were measured. Its maximum emission wavelength was 524 nm. The DMSO solution of S1 has bright yellow fluorescence. Respectively, to the S1 solution add F-, Cl-, Br-, I-, AcO-, H2PO4-, HSO4-, ClO4-, and SCN-, the fluorescent color of the solution didn't change. Only the CN- addition, the fluorescent color of the S1 solution changed from yellow to orange-red, indicating that S1 has good specific selectivity for CN-. The results of anti-disturbance experiment demonstrated that S1 detect CN- without interference from other anions. By calculation, the linear of the fluorescence of the sensor for CN- is 9.96×10-7. This value is lower than the World Health Organization (WHO) provisions of the cyanide content of drinking water. Mechanism studies show that S1 is a fluorescence sensor by reactive recognition CN-. In addition, the application of sensor S1 supported on solid silica gel was used as a solid material to detecting solid NaCN and CN- in pure water.

Key words: phenazine derivative, fluorescence sensor, detecting anions
