Abstract

A new rhodamine B derivative colorimetric and fluorescent double-sensor 1 has been investigated in this work. The sensor can select for Al³⁺ and Cu²⁺ in different systems. It exhibits highly sensitive recognition towards Al³⁺ in ethanol–H₂O (2 : 3, v/v) via a visible color change from colorless to pink and an appearance of orange fluorescence. Whereas, in CH₃CN–H₂O buffer (3 : 2, v/v), the sensor shows a significant fluorescent enhancement for Cu²⁺ over a wide range of tested metal ions. Finally, the sensor can be used to detect Al³⁺ and Cu²⁺ in natural water samples with a high accuracy.
