A novel silylated azo compound was synthesized and fully characterized. This compound was used in a chromogenic chemodosimeter approach for the highly selective detection of cyanide (CN–) in acetonitrile/water and in an aqueous micellar system. The anion breaks the Si–O bond, delivering a dye and causing a change in the color of the solution (from yellow to blue). The chemodosimeter was employed for the naked–eye and quantitative detection of CN– in tap water and cassava roots.
