Abstract
Highly selective binding and sensing of acetate over various monovalent ino rganic anions (MeCO2- much greater than H2PO4 > Cl-, Br-, I-, SCN-, NO3-, H SO4-, ClO4-) are achieved by N,N ' -bis(p-nitrophenyl)thiourea as a hydroge n-bonding chromoionophore in 1% water-99% MeCN (v/v), and acetic acid in vi negar is successfully determined by the complexation-induced chromogenic re sponse of this chromoionophore.
