title: Polymer complexes. LVI. Supramolecular architectures consolidated by hydrogen bonding and π-π interaction.
abstract: The amidation of aliphatic amine with acryloyl chloride in dry benzene as a solvent has been performed. Moreover, the polymer complexes have been prepared and structurally characterized by analyses, molar conductance measurements, magnetic susceptibility measurements, spectral techniques like IR, UV, NMR, ESR and thermal methods. Acryloyl hydrazine (AH) has been shown to behave as a bidentate ligand via its nitrogen (NH(2) of hydrazine group) and C-O/C=O (acryloyl group) in polymer complexes, all of which exhibit supramolecular architectures assembled through weak interaction including hydrogen bonding and π-π stacking .The magnetic and spectral data indicate a square planar geometry for Cu(2+) complexes and an octahedral geometry for Co(II) and UO(2)(II). The ESR spectral data of the Cu(II) complexes showed that the metal-ligand bonds have considerable covalent character. The thermal stability was investigated using thermogravimetric analysis. The results showed that the polymer complexes are more stable than the homopolymer.
