Theoretical and experimental study of organic nano-material for acetate anion based on 1, 10-phenanthroline

Abstract

New phenanthroline derivatives containing phenol groups have been synthesized and optimized. The nano-material involved bromine substituent was also developed which in the ortho-position of benzene ring. Their binding properties were evaluated for various biological anions (F -, Cl -, Br -, I -, AcO -and H 2 PO 4 -) by theoretical investigation, UV-vis, fluorescence, 1 H NMR titration experiments. These compounds all showed strong binding ability for AcO -without the interference of other anions tested. The anion binding ability could be regularized by electron push-pull properties of the ortho-or para-substituent on benzene. Theoretical investigation analysis revealed the effect of intramolecular hydrogen bond existed between -OH and other atoms in the structure of these compounds.
