Fluorogenic and Chromogenic Detection of Palladium Species through a Catalytic Conversion of a Rhodamine B Derivative
摘要:
A simple yet efficient detection method for palladium species is developed based on a molecular sensing system that undergoes a palladium-catalyzed oxidative addition. A rhodamine B derivative thus developed undergoes the catalytic process triggered by palladium insertion and gives both turn-on fluorescence and color changes. A usefulness of the sensing system is demonstrated by determining the residual palladium contents in a purified sample prepared through a palladium-catalyzed reaction.
