The schematic illustration of the photochromic multi-states sensing for multi-analytes metal ions detection with one spirooxazine sensor.
Three states (dark, UV irradiation and Vis irradiation) of spirooxazine-metallic coordination can be obtained by spirooxazine response with metal ions in different irradiation conditions.
