A fluorescent sensor for Al 3+ based on a photochromic diarylethene with a hydrazinobenzothiazole Schiff base unit

A highly sensitive and selective fluorescent probe for quantitative detection of Al3+ in food, water, and living cells

“…Table S1 † summarizes the detection limits of recently reported Al 3+ uorescent sensors and highlights their applications in food samples. [40][41][42][43][44][45][46] The detection limit of 2a toward Al 3+ is the lowest among these reported probes, implying that probe 2a can straightforwardly detect the concentration of Al 3+ in water samples and food samples.…”

Recent advances in small-molecule fluorescent photoswitches with photochromism in diverse states

“…90,91 The introduction of a photoswitch unit into ion recognition systems not only provides dual-channel response signals, but also apparently improves the detection selectivity and sensitivity to specific ions compared to traditional ion sensors. [92][93][94][95][96][97][98][99][100][101][102][103][104][105] To achieve this purpose, Lu et al 106 designed a diarylethenebased molecule functionalized with a pyrimidine hydrazone unit which have multi-controlled fluorescent switching and photochromic behaviours (Fig. 11).…”

A Novel Pyridine and Julolidine Based Chemosensor for Al3+ Detection

“…[15] 2-Aminopyridine is an important organic intermediate, mainly used in pharmaceuticals, dyes and organic sensors. [16] A variety of Schiff base chemosensors have been developed to recognize of Al 3 + , such as diarylethene, [17] naphthalimide, [18] and thiazole derivatives. [19] However, as far as we know, few julolidine-based Schiff base chemosensor has been reported.…”
