“…Compared with these common methods, fluorescent chemosensors have attracted significant attention in recent years due to their operational simplicity, low cost, naked eye detection, real-time monitoring, time saving, high selectivity, and sensitivity [14,15,16,17,18,19,20,21,22,23,24]. However, the development of fluorescent chemosensors for Al 3+ is relatively lagging behind because of its strong hydration ability in water, poor coordination ability and the lack of suitable spectroscopic characteristics [25,26,27].…”

The development of highly selective and sensitive chemosensors for Al3+ detection in pure aqueous solution is still a significant challenge. In this work, a novel water-soluble polymer PEGBAB based on salicylidene Schiff base has been designed and synthesized as a turn-on fluorescent chemosensor for the detection of Al3+ in 100% aqueous solution. PEGBAB exhibited high sensitivity and selectivity to Al3+ over other competitive metal ions with the detection limit as low as 4.05 × 10−9 M. PEGBAB displayed high selectivity to Al3+ in the pH range of 5–10. The fluorescence response of PEGBAB to Al3+ was reversible in the presence of ethylenediaminetetraacetic acid (EDTA). Based on the fluorescence response, an INHIBIT logic gate was constructed with Al3+ and EDTA as two inputs. Moreover, test strips based on PEGBAB were fabricated facilely for convenient on-site detection of Al3+.

“…Recently, the fluorescent method has become popular due to its operational simplicity, high selectivity and sensitivity, real-time response and naked eye detection. Most of the sensors are rhodamine derivatives [40][41][42][43][44][45], naphthol derivatives [46][47][48], quinoline derivative [49]. Some are based on julolidine and tryptophan moieties [50], conjugated copolymer-ATP supramolecular complex [51], Organic Framework [52]，gold nanoparticles [53,54].…”

“…A lot of effort has been devoted to designing and synthesizing of new fluorescent chemosensors for metal ions in the past few years [5][6][7][8][9]. However, most of these studies are stressed on the design of selective and sensitive fluorescent probes used only in solution phase, which is hard to realize repetitive application.…”

Abstract:A new and easy-to-make polymer film sensor was prepared by dip-coating technique and this film used as fluorescent chemosensor for the detection of metal ions in aqueous solution. The proposed film sensor exhibited dual emissions at 540 and 582 nm under a single excitation wavelength. The fluorescence behavior of this film sensor toward metal ions has been investigated using these two wavelengths. The proposed sensor was found to show selectivity and sensitive to Fe 3+ ion when compared the other metal ions in deionized water with excellent photostability. Detection limit of the polymeric film sensor was calculated as 86.15 and 28.90 μM. The results showed that the sensor can be successfully applied to the determination of Fe 3+ ions in aqueous media. Contact angle measurement of PAZU film probe was also investigated and the result showed that the proposed film probe has hydrophobic property.
