A new non-natural receptor 2,2′-[benzene-1,2-diylbis(iminomethanediyl)]diphenol (4) was synthesized, and it is fluorogenic behaviour toward various metal ions were investigated. Receptor 4 exhibited pronounced fluorescence ...

An imine-linked dipodal Zn2+ complex has been synthesized and elevated its binding affinity towards library of metal ions (Cr3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+ and Bi3+). The recognition properties ...

A colorimetric and fluorescent ‘on–off’ chemosensor 1 was developed for the selective and sensitive detection of Cu2+ over the other examined metal ions. Upon addition of Cu2+, sensor 1 exhibits moderate enhancement in the ...

A dipodal fluorescent receptor, 2,2’-[ethane-1,2-diylbis(iminoethane-1,1-diyl)]diphenol (2), with amine and hydroxyl moieties as binding sites has been synthesised and characterized with spectroscopic methods and single ...

A linear Schiff-based receptor (L) containing two imino phenol units was developed for the selective fluorescent sensing of Zn2+ with a discriminating enhancement of 12-folds over the other surveyed cations. Within the ...

A novel cell-permeable urea-linked dipodal naphthalene-based fluorescent receptor 1 (1,1׳-(1,5,5-trimethyl-3-oxocyclohexane-1,2-diyl)bis(3-(naphthalen-2-yl)urea) was designed and synthesized. The cation recognition ability ...

A malonohydrazide derivative bearing an imine and phenolic group was synthesized and had a high affinity and selectivity towards Zn2þ. The recognition properties of receptor 1 were evaluated using absorbance and fluorescence ...
