Naphthalene Flanked Diketopyrrolopyrrole: A New Functional Dye Based Optical Sensors for Monitoring Cyanide Ions in Water

Cyanide (CN − ) is one of the most hazardous ions to humans and the environment. Therefore, sensitive, and selective sensors for CN − monitoring are highly required. A novel chemosensor based on naphthalene flanked diketopyrrolopyrrole dye (TBC‐DPPN) is synthesized for the direct detection of CN − in water samples by naked eye and vibrational spectroscopy (UV–Vis and fluorescence). The electron deficient carbonyl group of the lactam ring of...
