“…[37,38] The spectra of [Mn(AHQMBSH) 2 2 ] was not well resolved, it was not well interpreted, but its magnetic moment value shows that it is diamagnetic in nature, as expected. [28] The results of the magnetic moment value (Table 1) were shown to have octahedral geometry for all the M(II) oxinates. Hence, the observed values of magnetic moments and the electronic spectra of M(II) oxinates supported octahedral geometry for all the structures.…”

“…Further, the initial thermal degradation in all of the polymeric chelates starts below 150 C. This may be due to the removal of hydrated water, whereas weight loss obtained in the temperature range of 150-200 C might be due to the presence of two coordinated water molecules [30,38]. The rate of decomposition for the entire polymeric chelates is initially low, up to 150 C. Eventually, the maximum rate of decomposition with 64-84% weight loss was observed in the temperature range of 300-400 C for polymeric chelates of Cu þ2 and 70-84% weight loss was observed in the temperature range of 400-450 C for polymeric chelates of Ni þ2 and Co þ2 metal ions, while that of 60-85% weight loss was observed in the temperature range of 450-550 C for polymeric chelates of Mn þ2 and Zn þ2 metal ions.…”

New ethylenebismaleimide-diamine oligoimide-II (EBMDDMCMHQ) containing 8-hydroxyquinoline as a pendent group(s) was prepared using ethylenebismaleimidediamine oligoimide-I (EBMDDM) and 5-chloromethyl-8-hydroxyquinoline hydrochloride (CMHQ) in the presence of base catalyst. Ethylenebismaleimide-diamine oligoimide-I (EBMDDM) was prepared by the Michael addition reaction of ethylenebismaleimide (EBM) and 4,4 0 -diaminodiphenyl methane (DDM). The resulting oligoimide-II (EBMDDMCMHQ) was characterized by spectral techniques. Polymeric metal chelates of oligoimide-II were prepared using transition metal ions and were duly characterized. Ion-exchange properties of oligoimide-II for Fe(III), Zn(II), Ni(II), and Cu(II) metal ions were also studied by batch-equilibration method. It has good metal ion uptake capacity at varying pH ranges.

“…The synthesized copolymer was used to prepare a series of five polymeric chelates using Zn(II), Cu(II), Ni(II), Co(II), and Mn(II) metal ions. The thermogravimetric analysis (TGA) of parent ligand and its metal chelates have showed remarkable variation in the mode of thermal decomposition and their thermal stabilities [8]. The polycondensation of 2-hydroxy-4-ethoxybenzophenone with 1,3-butane-diol was carried out in the presence of polyphosphoric acid.…”

Terpolymer metal complexes involving transition metal ions such as Cu(II), Mn(II) and Zn(II) were prepared using a terpolymer ligand derived from anthranilic acid-phenyl hydrazine-formaldehyde (APHF). The terpolymer ligand and its metal complexes were intended to spectral characterizations viz. FTIR, electronic, ESR, 1 H NMR and 13 C NMR to elucidate the structural confirmations. The number, weight, and size average molecular weights of the terpolymer ligand were determined by gel permeation chromatography (GPC). The empirical formula of the repeating unit for both the terpolymer ligand and its metal complexes was clearly justified by elemental analysis. The thermal stability of the ligand and its metal complexes was established by thermogravimetric analysis (TGA). On basis of the TGA data, the kinetic and thermodynamic parameters such as activation energy (E a ), order of reaction (n), entropy change (DS), apparent entropy (S*), frequency factor (Z) and free energy change (DF) were calculated using Freeman-Carroll and SharpWentworth methods. Further the degradation mechanism for the thermal decomposition was also identified from Phadnis-Desphande method. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis were used to establish the surface morphology and nature of the terpolymer ligand and its metal complexes. In addition, the terpolymer ligand and its metal complexes were screened against the growth of few bacteria and their inhibitions were measured and reported.
