A Novel Series Colorimetric and Off–On Fluorescent Chemosensors for Fe3+ Based on Rhodamine B Derivative

A novel series colorimetric and off–on fluorescent chemosensors ( 2a , 2b , 2c ) were designed and synthesized, which showed reversible and highly selective and sensitive recognition toward Fe 3+ over other examined metal ions. Upon addition of Fe 3+ , sensors ( 2a , 2b) exhibit remarkably and 2c ex...

Description
Summary:A novel series colorimetric and off–on fluorescent chemosensors ( 2a , 2b , 2c ) were designed and synthesized, which showed reversible and highly selective and sensitive recognition toward Fe 3+ over other examined metal ions. Upon addition of Fe 3+ , sensors ( 2a , 2b) exhibit remarkably and 2c exhibits moderate enhanced absorbance intensity and color change from colorless to pink in CH 3 OH–H 2 O(1:1, v/v). The three compounds ( 2a , 2b , 2c ) may therefore be applicable as rhodamine-based turn-on type fluorescent chemosensors.
