title: Coumarin-derived transformable fluorescent sensor for Zn2+.
abstract: We report a coumarin-derived fluorescent sensor for Zn(2+) termed CTS. CTS shows excellent binding selectivity for Zn(2+) over competing metal ions due to the transformable ability of CTS, that is the displacement of other metal ions by Zn(2+), which induces transformation of chelation from an amide to an imidic acid tautomeric form.
