Novel hybrids of Cu2+ ternary complexes of salicylidene-amino acid Schiff base with phenanthroline (or bipyridine) intercalated in Mg/Al-NO3-layered double hydroxide

Four Cu2+ complexes of salicylidene-amino acid Schiff base with 1,10-phenanthroline (Phen) or 2,2′-bipyridine (Bipy) were successfully intercalated in interlayer galleries of Mg/Al-NO3-layered double hydroxide (LDH) by the swelling-restored method. The hybrids were characterized by elemental analysis, X-ray diffraction, FT-IR spectra, UV–vis DRS, TG–DTA and SEM observation. Good protection of the complexes by LDH in neutral and weak acidic solutions was revealed by UV spectra, cyclic voltammograms and luminescence spectra.
