Abstract

This research project aims to synthesize new coordination polymers through the complexation of low-cost metal salts, namely copper (II) and nickel (II), with organic ligands containing imine groups. The ligands will be synthesized by reactions between an aldehyde or an ketone and a primary amine, then purified by recrystallization and finally structurally characterized. After this step, the preparation of the coordination polymers with be performed by reactions between ligands and metals, which may be made under ambient or solvothermal conditions. Once the complexes are synthesized, they will be characterized by several techniques such as simultaneous thermogravimetry and differential thermal analysis, electronic spectroscopy, vibrational spectroscopy in the infrared region, 1H and 13C nuclear magnetic resonance and single-crystal X-ray diffractiometry. Depending on the characteristics of each compound, further studies may be performed involving potential applications as sensors or sorbents for gases.
