Development of a bisphenol A based chemosensor for Al and its application in cell imaging and plant root imaging.

Bisphenol A is a fluorophoric platform that is used to develop chemosensors for various species. Herein, we report a bisphenol A based Schiff-base molecule, 4,4'-(propane-2,2-diyl)bis(2-(()-((2-hydroxy-5-methylphenyl)imino)methyl)phenol) (Me-HL), as a selective chemosensor for Al. Among the several metal ions, it shows a significant increment in its fluorescence intensity (50 fold) at 535 nm in the presence of Al ions.

Modulation of aluminum sensing properties of a sulphone group containing chemosensor and its biological applications.

A chemosensor with two binding pockets facilitates binding of one metal ion in either of the pockets providing a better chance for the interaction and hence recognition of the cation. We report here a chemosensor, namely 2,2'-(1E)-(5,5'-sulfonylbis(2-hydroxy-5,1-phenylene))bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)dinaphthalen-1-ol (HL-naph), for selective sensing of Al in DMF- HEPES buffer (1:4, v/v, pH 7.4).
