title: Highly sensitive cyanide anion detection with a coumarin-spiropyran conjugate as a fluorescent receptor.
abstract: A coumarin-spiropyran conjugate (2) shows a CN(-)-selective fluorescence enhancement under UV irradiation. This enables accurate determination of very low levels of CN(-) (>0.5 μM).
