Cyanide detection in purewater is important for many applications. We present a novel type of chemodosimeter azo dye developed on the basis of the benzophenone as the electrophilic receptor of the cyanide anion and a saccharidic moiety to render the dye water soluble. This chemodosimeter is found to be highlyselective and tunable toward only cyanide in purewater.

amounts of 4-aminobenzophenone and 4-nitrobenzophenone. Both α-phenyl-2-nitrobenzenemethanol (9) and 3, 5-dimethyl-4-nitrobenzenemethanol (10a) did not react with 1 M sodium hydroxide, presumably due to steric hindrance. α-(p-Nitrophenyl)-4-pyridinemethanol (14) and its N-oxide 11 with 1 M sodium hydroxide yielded 4,4′-diaroylazoxybenzenes 15a and 12a, respectively, 4,4′-diaroylazobenzenes 15b and 12b, respectively
