Phosphonium and ammonium fluorescein for selective detection of HSO 4 − and CN − ions in aqueous media

Key Points

• This research aims to create fluorescein-based chemosensors for the selective detection of bisulfate and cyanide ions in aqueous solutions.
• Synthesis of fluorescein-based anionic chemosensors
• In vitro testing in aqueous media
• Detection of HSO4− and CN− ions
• Successfully synthesized fluorescein- l -3-phenyl-2-aminopropyl trimethylammonium tosylate
• Successfully synthesized triphenylphosphonium tosylate
• Both chemosensors selectively detect bisulfate and cyanide ions in water.
