通过罗丹明开环反应和比率位移法合成了一种新型的含1，8-萘酰亚胺基的罗丹明衍生物（1），并将其作为双模式Cu（2+）选择性传感器.当Cu（2+）取代1-Zn（2+）络合物中的Zn（2+）时，可观察到Cu（2+）通过1中罗丹明开环的比色和“关-开”信号以及比率荧光信号输出。
A new rhodamine-based derivative bearing a 1,8-naphthalimide group (1) was synthesized as a dual-mode Cu(2+)-selective sensor via the rhodamine ring-opening approach and ratiometric displacement. A colorimetric and "off-on" signal for Cu(2+) through rhodamine ring opening in 1 and ratiometric fluorescent signal output when Cu(2+) displaces the bound Zn(2+) in the 1-Zn(2+) complex can be observed.
