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.
开发了一种基于分子传感体系的钯物种简便高效的检测方法，该体系经历钯催化的氧化加成。所开发的罗丹明 B 衍生物通过钯插入触发催化过程，产生荧光和颜色的双信号转变。通过测定钯催化反应制备的纯化样品中的残留钯含量，验证了传感体系的实用性。
