摘要：

A new rhodamine B-based dual-function chromo-and fluorogenic probe for Cu2+ and ClO- has been designed, synthesized, and characterized. The probe comprises a spectroscopic unit of rhodamine B and a Cu2+-specific chelating unit of pyridinecarboxamide as well as a ClO--specific reactive moiety of diacylhydrazine, and is a highly selective and extremely sensitive fluorescent and colorimetric sensor for Cu2+ and ClO- in different pH conditions. Compared with the reported probes for Cu2+ or ClO-, this is the first chemosensor based on a small molecule that can detect both Cu2+ and ClO-, respectively, at 1 nM level.
