Abstract
A new rhodamine-based derivative bearing a 1,8-naphthalimide group (1) was synthesized as a dual-mode Cu2+-selective sensor via the rhodamine ring-opening approach and ratiometric displacement. A colorimetric and "off-on" signal for Cu2+ through rhodamine ring opening in 1 and ratiometric fluorescent signal output when Cu2+ displaces the bound Zn2+ in the 1-Zn2+ complex can be observed.
