Cu2+-selective ratiometric and "off-on" sensor based on the rhodamine derivative bearing pyrene group.
A new rhodamine-based derivative bearing a pyrene group (PRC) was synthesized as a ratiometric and "off-on" chemosensor for Cu(2+). PRC displayed a selective and chelation enhanced ratiometric fluorescence change and colorimetric change with Cu(2+) among the metal ions examined.
