| description | A new and simple colorimetric receptor

, based on 2,3-diaminomaleonitrile and julolidine moieties, has been synthesized and characterized.
1
showed a selective colorimetric sensing ability for copper(
ii
) ions by changing color from yellow to colorless, and could be utilized to monitor Cu
2+
over a wide pH range of 4-12. The detection limit of
1
(2.1 μM) for Cu
2+
ions is much lower than that recommended by WHO in drinking water (30 μM). Moreover, the receptor
1
can also detect fluoride by color change from yellow to orange, distinguishing the fluoride ions effectively from anions such as CH
3
COO
−
and CN
−
. It was also found that the
1
-F
−
complex was reversibly bound and could be simply reverted back through treatment with a proper reagent such as HCl. The sensing mechanism for F
−
was theoretically supported by DFT and TD-DFT calculations.
