We developed an azo dye-based chemodosimeter possessing oxime functionality as a reaction unit with cyanides in the aqueous environment. The azo oxime chemical probe rapidly reacted with cyanides through the nucleophilic addition and subsequent proton transfer of resonance-assisted hydrogen bonding OH, which displayed a dramatic color change from colorless to dark violet in DMSO/HEPES buffer.
