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

Abstract

New phenanthroline derivatives (1, 2, 3, 4) containing phenol groups have been synthesized and optimized. The nano-material of compound 2 was also developed. Their binding properties were evaluated for various biological anions (F–, Cl–, Br–, I–, AcO– and H2PO4–) by theoretical investigation, UV-vis, fluorescence, 1HNMR titration experiments and 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.
