A Multi-Stimuli responsive organic luminogen with aggregation induced emission for the selective detection of Zn2+ ions in solution and solid state

Structural isomerism induces pH dependent AIE-coupled ESIPT: an in-depth spectroscopic exploration with application in amine vapor sensing

“…[18][19][20][21] Quite expectedly, the aforementioned ESIPT-AIE active probes have found use as reversible chemosensors, chemodosimeters as well as cell imaging agents. [22][23][24] However, one principal bottleneck in the research and development of this class of fluorophores is the lack of in depth analysis of the underlying photophysical processes and focus has been maximized on the application of ESIPT-AIE active probes.…”

Recent Developments in the Detection of Zn2+ Ions Using Schiff Base Probes

“…The limit of determination was found to be 112 M and the authors also designed a test paper strip for rapid detection of Zn 2+ ions. A responsive multi-stimulated organic fluorescent compound 2 (Figure 1) was synthesized by Francis Joy and her research group 48 for the detection of Zn 2+ ions in a waterbased solution. This hydrazone-based Schiff base turn-on chemosensor was highly sensitive and selective in nature towards the Zn 2+ ion.…”

Multiple fluorescence and hydrogen peroxide-responsive properties of novel triphenylamine–benzothiazole derivatives

“…This rapid four-level cycle in the BZT molecule usually gives rise to two emission bands: a short-wavelength emission caused by Enol* attenuation (normal emission, Enol FL) and a longer emission caused by the Keto* form (ESIPT emission, Keto FL). 29,30 As compared to normal uorophores, the ESIPTbased dyes have a larger Stokes shi, which can avoid selfabsorption and the inner lter effect, thus improving the uorescence analysis performance. 31 According to the ESIPT mechanism, the uorescence properties of the benzothiazole skeleton are highly dependent on the solvent environment due to the altered intramolecular hydrogen bonds.…”
