Abstract

The complexing and selective binding constants of Eu(fod)(3) with bis(2'-ethylbenzoate) ethylene glycol podands having one to four oxyethylene groups was observed on their H-1-NMR spectra at 250 MHz and 295 K in CDCl3. The Eu(fod)(3) interaction displayed the selective binding role of oxygen on H2C-O-CH2 backbones with referring the H-1 chemical shifts.
