dc.description | A novel Schiff base (L1) derivative from cinnamaldehyde with a simple structure was synthesized and evaluated as a sensitive colorimetric Ni2+ sensor in aqueous solution. Addition of nickel dissolved in water into a L1 solution produced a rapid color change from faded yellow to deep orange, corresponding to a large red shift in the absorption peak from 435 to 480 nm. L1 exhibited a detection limit for Ni2+ in water of 1 × 10−7 M measured by absorption spectroscopy, whereas by naked eye the detection limit was of the order of 5 × 10−6 M. Interaction between L1 and other biologically and environmentally relevant metal ions such as Hg2+, Pb2+, Co2+, Cu2+ and Mn2+, induced minimal spectral changes. These results show that the Schiff base L1 could be an excellent Ni2+ chemosensor with high metal selectivity and with the capability to perform the detection in water over a pH range of 5.5–8. | |
