“…As can be seen from table I, most of these methods have different performance values for good sensitivity. However, in comparison with other methods, this sensor has comparatively more sensitivity and lower detection limit value compared to other fluorescent sensors [61][62][63][64][65].…”

“…8-Hydroxyjulolidine-9-carboxaldehyde is a well-known chromophore used in fluorescence chemosensors, and chemosensors with the julolidine moiety are usually soluble in aqueous solutions (Narayanaswamy & Govindaraju, 2012;Maity et al, 2011;Na et al, 2013;Noh et al, 2013). Compounds containing a julolidine group exhibit chromogenic naked-eye detection of copper, zinc, iron and aluminium ions as well as fluoride ions (Choi et al, 2015;Wang et al, 2013a,b;Kim et al, 2015;Jo et al, 2015). There are many reports in the literature on 8-hydroxyjulolidine-9-carboxaldehyde-based Schiff bases and their application as metal sensors (Park et al, 2014;Lee et al, 2014;Kim et al, 2016).…”

“…Julolidine is chemically an aniline derivative with two N-alkyl substituents forming rings back to the aromatic ring; the fused rings lock the nitrogen lone-pair of electrons into conjugation with the aromatic ring leading to unusual reactivity. The presence of the julolidine ring system in some molecules makes them useful for chromogenic naked-eye detection of copper, zinc, iron and aluminium ions as well as fluoride ions (Wang et al, 2013;Choi et al, 2015;Kim et al, 2015;Jo et al, 2015). Julolidine dyes exhibit excited-state intramolecular proton transfer (Nano et al, 2015).…”
