“…To further evaluate the unusual characteristics of L‐1 and L‐2 , Table s1 (see Supporting Information) had been created to get a visualized look on different aspects of some recently published sensors for Al 3+ detection. As shown in Table s1, each sensor had certain advantages, such as rare interference,, low detection limits,,,,, single‐step synthesis,, and applicability in live cell imaging ,,,,. In our work, L‐1 and L‐2 exhibited many favorable analytical characteristics, such as absence of interference, high selectivity, and applicability in live cell imaging.…”

“…Importantly, upon addition of Al 3+ , an obvious fluorescence enhancement was observed (Figure S2). The observed fluorescence enhancement of the sensors ( L‐1 and L‐2 ) toward the addition of Al 3+ was immediate and the intensity remarkably enhanced which may be attributed to the inhibition of photoinduced electron‐transfer (PET) effect and the formation of a chelate complex between metal ion and sensor, causing the CHEF effect ,. These results indicated that L‐1 and L‐2 were good fluorescent sensors toward Al 3+ over other metal ions and could serve as the sensitive fluorescent sensors for Al 3+ in aqueous solution.…”

Two novel highly selective fluorescent sensors L‐1 and L‐2 for the determination of Al3+ ion were synthesized and characterized. The sensors acridine‐4,5‐diylbismethyl(bis(oxy))bis(2,1‐phenylene))bis‐(methylene))bis(azanediyl))bis(3‐phenylpropan‐1‐ol) (L‐1) and 2,2′‐acridine‐4,5‐diylbis(methylene(bis(oxy))bis(2,1‐phenylene))bis‐(methylene))bis(azanediyl))bis(propan‐1‐ol) (L‐2) showed “turn on” fluorescence response in the presence of Al3+ ion in DMSO/tris‐HCl (1:1, v:v, pH=7.2) buffer solution. Other cations viz. Li+, Na+, K+, Mg2+, Ca2+, Fe2+, Co2+, Ni2+, Cd2+, Cu2+, Zn2+, Mn2+, Ba2+, Pb2+, Hg2+, Fe3+ and Eu3+ ions showed no appreciable change in fluorescence spectrum. The detection limits of L‐1 and L‐2 for Al3+ ion were at the parts per billion level. In addition, possible utilization of sensors as bio‐imaging fluorescent sensors to detect Al3+ in human cervical HeLa cells was also investigated by confocal fluorescence microscopy.

“…Previously, there are some "turn-on" fluorescent probes containing C=N bond for detecting some trivalent metal ions (for example, Al 3+ ) based on chelating trivalent metal ions to prevent the C=N isomerization or/and PET (photoinduced electron transfer) process. [24][25][26] However, there is no probe simultaneously detecting multiple trivalent ions on account of the hydrolysis of the imine group. Herein, we designed and synthesized a new Schiff base L benzene-1,4-diylbis[N-(naphthalen-1-yl)methanimine] derived from naphthylamine and terephthalaldehyde in a simple approach as fluorescent sensor for trivalent metal ions.…”

A simple and easily synthesized fluorescent sensor L, based on condensation reaction of 1-Naphthylamine and terephthalaldehyde, was synthesized and characterized systemically. Both UV-vis and fluorescence spectroscopic studies indicated that the sensor L showed good selectivity toward trivalent metal ions (such as Al 3+ , Fe 3+ , Cr 3+ , La 3+ and Ce 3+) over other monovalent or divalent metal ions. The sensing mechanism was suggested that the trivalent ion promoted the hydrolysis of Schiff base. Meanwhile, took the common trivalent ions Al 3+ , Fe 3+ and Cr 3+ as examples, limit of detection (LOD) values of sensor L were calculated to be 1.23, 0.94 and 1.14 nM for Al 3+ , Cr 3+ and Fe 3+ , respectively, suggesting very high sensitivity towards the cations which could make it attractive in trivalent metal ions detection.
