A highly selective ratiometric fluorescent probe, which contains an aminonaphthalimide fluorophore and a self-immolativespacer for 1,4-dithiothreitol (DTT) detection was designed and synthesized. The probe displays a 66 nm red-shift of fluorescence emission and the color changes from colorless to jade-green upon reaction with DTT. These properties are mechanistically ascribed to the strong reducing
