title: Development of fluorescent sensing of anions under excited-state intermolecular proton transfer signaling mechanism.
abstract: [reaction: see text] A substantially red-shifted fluorescence emission in 3-hydroxyl-2-naphthanilide in acetonitrile was developed and drastically enhanced upon addition of anions such as F(-), AcO(-), and H(2)PO(4)(-), with the enhancement depending on anion basicity. Excited-state intermolecular proton transfer in the sensor-anion hydrogen-bonding complex was suggested to be the signaling mechanism.
