Abstract:
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 crystal X-ray techniques. The recognition of the anions with receptor 2 was studied
using UV-Vis and fluorescence spectroscopy. The 1
H-NMR spectroscopic and DFT studies revealed the
distinct recognition of I− ions over the other surveyed anions.
