Anion-dependent fluorescence in bis(anilinoethynyl)pyridine derivatives: switchable ON–OFF and OFF–ON responses

Author affiliations

Abstract

Urea and sulfonamide derivatives of 1 exhibit ON–OFF and OFF–ON switchable fluorescent and colorimetric responses upon protonation. The magnitude of the fluorescence event is dictated by the anion, resulting in a rare, fully organic “turn-on” fluorescent sensor for chloride.
