Schiff base polymers: preparation, spectral, thermal and their in vitro biological investigation, Designed Monomers and Polymers, 17, 217 (2014).
The
Schiff base ligand and its metal (III) complexes showed antibacterial activity against E.
Schiff base compounds are able to form stable complexes with several transition metal ions [28].
Physical characteristics and elemental analysis of
Schiff base L-1.
1H NMR spectra of the products showed doublet signals at 5.68 and 5.71 ppm (P-12, in CD[Cl.sub.3] and in DMSO-[d.sub.6], respectively) and 5.69 ppm (P-13, in CD[Cl.sub.3]) with [sup.2]JPH about 23 Hz which can be assigned to the CHP proton from their units formed by addition reaction between the polymeric H-phosphonate and the
Schiff base. The NH proton signal is masked in the spectra taken in CD[Cl.sub.3] solution.
In Figure S2, a very strong band is below 400 nm for
Schiff base (303 nm) and at 344 nm for complexes, due to ligand-centered [pi] [right arrow] [[pi].sup.*]/[pi] [right arrow] [[pi].sup.*] (most probably from phenolate oxygen donor atom) transitions (LLCT).
Recently, Al-Shemary and Zaidan [5] reported the successful synthesis and characterization of a new tetradented
Schiff base ligand known as 2,2'(1E,1'E)-(ethane-1,2-diylbis (azan-1-yl-1-ylidene))bis(phenylmethan-1-yl-1-ylidene)dibenzoic acid (EDA2Bb) and its [Cu.sup.II], [Ni.sup.II], [Mn.sup.II], [Co.sup.II], and [Hg.sup.II] complexes.
Mass spectrum of the furan
Schiff base ligand (H-MFMAQ) (Figure 1(a)) has final peak at 268 amu corresponding to the furan
Schiff base ligand moiety [[C.sub.15][H.sub.12][N.sub.2][O.sub.3]] (atomic mass 268 amu) (Scheme 2).
Cobalt complexes with
Schiff bases have received considerable attention in the fields of coordination chemistry and biological chemistry (6).
Salicylaldehyde-hydrazine hydrate
Schiff base (la) showed the better inhibition to the growth of S.
In addition, the antibacterial activities of both hydrazone
Schiff base L1 and Zn(II) complex have also been examined.
