“…Choi et al [73] reported a dual-channel sensor 44 equipped with julolidine and imidazole moieties as binding and signaling units, respectively. The fluorogenic mode could show instant responses toward Zn 2+ and Al 3+ ions in terms of selective emission enhancement.…”

“…Choi et al have synthesised a Schiff base from 8-hydroxyjulolidine-9-carboxyaldehyde and 1-(3-aminopropyl) imidazole which can colourimetrically detect Fe (II) and Fe(III), while also sensing Zn(II) and Al(III) fluorescently. 17 The Schiff base changed from colourless to orange 60 upon coordination with Fe(II), and to purple with Fe(III). Meanwhile, Zn(II) was the only metal ion (amongst 17 tested) that increased the emission intensity of the Schiff base in a mixture of water and acetonitrile.…”

As a result, SERS has the potential to develop relatively simple and sensitive methods of detecting and quantifying a range of metal ions in solution. This could be beneficial for the environmental monitoring of potentially toxic metals (PTMs). Here, salen was used as a ligand to form complexes of Ni(II), Cu(II), Mn(II) and Co(II) in solution. The SERS spectra showed 10 characteristic spectral differences specific to each metal complex, thus allowing the identification of each of these metal ions. This method allows a number of metal ions to be detected using the same ligand and an identical preparation procedure. The limit of detection (LOD) was determined for each metal ion, and it was found that Ni(II), Cu(II) and Mn(II) could be detected below the WHO's recommended limits in drinking water at 1, 2 and 2 µg L -1 , respectively. Co(II) was found to have an LOD of 20 µg L -1 , however 15 no limit has been set for this ion by the WHO as the concentration of Co(II) in drinking water is generally <1-2 g L -1 . A contaminated water sample was also analysed where Mn(II) was detected at a level of 800 µg L -1 .

“…In this regard, a julolidine moiety is a well-known chromophore and chemosensors with the julolidine moiety are usually water-soluble (Choi et al, 2014). Moreover, we expected that the presence of carboxylate group (a hard base) in a chemosensor might not only increase its water solubility, but also would make the molecule more selective toward a hard acid, such as Al 3 þ .…”
