✦ Synopsis

Highly selective binding and sensing of acetate over various monovalent inorganic anions (MeCO 2 -H 2 PO 4 ->Cl -, Br -, I -, SCN -, NO 3 -, HSO 4 -, ClO 4 -

) are achieved by N,N%-bis(p-nitrophenyl)thiourea as a hydrogen-bonding chromoionophore in 1% water-99% MeCN (v/v), and acetic acid in vinegar is successfully determined by the complexation-induced chromogenic response of this chromoionophore.
