Synthesis, Spectroscopic Characterization and Thermal Studies of Polymer-Metal Complexes Derived from Modified Poly Styrene-Alt-(Maleic Anhydride) as a Prospects for Biomedical Applications

Abstract

Eight polymer-metal complexes were synthesized from complexation of divalent Mn(II), Ni(II), Co(II), and Cu(II) metal ions with modified polystyrene-alt-(maleic anhydride) (PSMAP and PSMAM) ligands. The structures of these new complexes were characterized using a variety of techniques, including magnetic moment susceptibility, conductance measurements, FT-IR spectroscopy, ultraviolet-visible (UV-VIS), thermogravimetric analysis (TGA), as well as scanning electron microscopy (SEM). All metal-polymer complexes have a non-electrolytic nature based on conductance measurements. The polymer molecule behaves as neutral bidentate NO ligand through O atoms of carbonyl (C=O) and N atoms of amide (O=C-NH). Divalent Mn2+, Ni2+, Co2+ and Cu2+ complexes have an octahedral geometry based on their electronic spectra and magnetic values. Based on thermal analysis data, those new complexes are more thermally stable than the ligands. SEM and TEM are manipulated to give the surface structure and the particle size measurements where they give different shapes and sizes of the synthesized complexes.

“…These characteristics make it valuable for applications in which durability and reliability are essential. This copolymer has found diverse applications across multiple domains, such as drug delivery, biomedical applications, dye separation, and heavy metal separation. , SMA has potential advantages in different fields, but its specific benefits in optoelectronic applications have not yet been extensively explored. Some critical properties of SMA, including exceptional optical transparency, particularly within the visible light range, make it have great potential and are highly suitable for transparent and colorless EC applications such as lenses, windows, and optical films, which are prime candidate areas where SMA could be utilized.…”
