Abstract
A new chemosensor based on rhodamine B thiohydrazide is described. Chemosensor B was found to show a reversible dual chromo- and fluorogenic response toward Hg2+ in aqueous solution in a highly selective and sensitive manner. This was suggested to result from the coordination of Hg2+ at the N, S binding sites in B to open its spiro ring.
摘要
描述了一种基于罗丹明B硫酰肼的新型化学传感器。发现化学传感器B在水溶液中对Hg2+表现出可逆的双色和荧光响应，具有高度的选择性和灵敏性。这被认为是由于Hg2+在B中的N、S结合位点配位以打开其螺环所致。
