Biocompatible Molybdenum Complexes Based on Terephthalic Acid and Derived from PET: Synthesis and Characterization

Metal-organic molybdenum complexes were synthesized by the hydrothermal method using ammonium heptamolybdate as metallic source, and organic ligand terephthalic acid (BDC) or bis(2-hydroxyethyl) terephthalate (BHET), obtained via glycolysis of poly(ethylene)terephthalate (PET). The BDC-Mo BHET-Mo characterized XRD, N2 physisorption, TGA, ATR-FTIR, SEM, XPS their in vitro biocompatibility was tested porcine fibroblasts viability. results show that molybdates (MoO4-2) are coordinated to carbonyl functional groups BDC BHET urea bonding (-NH-CO-NH-) which is related high thermal stability. These molybdate possess rectangular prism particles made up rods arrays characteristics oxides (MoO3). do not be cytotoxic for dermal growing on surface 48 h culture.
