A novel, easily available colorimetric and fluorescent double-sensor 1 based on Salicylaldehyde bis-Schiff has been investigated in this work. The sensor exhibits highly selective and sensitive recognition toward Cu2+ in aqueous solution via a naked eye colour change from colourless to yellow and toward Al3+ via a significant fluorescent enhancement in ethanol over a wide range of tested metal ions. This represents the first reported Salicylaldehyde Schiff-based sensor capable of detecting both Cu2+ and Al3+ using two different modes.
A novel chemosensor based on Salicylaldehyde bis-Schiff has been investigated. The sensor exhibits colour change from colourless to yellow toward Cu2+ in aqueous solution. It exhibits a significant fluorescent enhancement toward Al3+ in ethanol. It also exhibits aggregation-induced emission enhancement (AIEE) characteristics.Figure optionsDownload as PowerPoint slideHighlights
