Selective fluorescence sensing of Cu(ii) and Zn(ii) using a new Schiff base-derived model compound: naked eye detection and spectral deciphering of the mechanism of sensory action
Two polymers, linear P1 and cross-linked P2, are employed in anion sensing. P1 exhibits fluorescence sensing of HPPi with a detection limit of about 1.63 ppm in aqueous DMSO. P2 exhibits selective naked-eye detection of PPi/HPPi via an indicator displacement assay (IDA).
The cholesterol appended hydroxybenzaldehyde derived Schiff bases1–4have been designed and synthesized. They are suitable for the naked-eye detection of metal ions such as Hg2+and Ag+using sol–gel methodology involving either rupturing or maintaining the imine bonds.
A T-shaped Schiff-base triazatruxene derivative (TATNFF) was designed, synthesized, and explored as a sensitive probe to detect HCl gas by the naked eye.
