A new poly(azomethine) with improved solubility was successfully prepared by the polycondensation of terephthalaldehyde and 2,2-Bis[4-(4-aminophenoxy)phenyl]-hexafluoropropane (4-BDAF) under green chemistry conditions. This polymer containing hexafluoroisopropylidene compared a isopropylidenediphenyl to study influence presence fluorine atoms on properties polymer. Both were characterized nuclear magnetic resonance (NMR), their molecular weight measured gel permeation chromatography (GPC), morphology studied X-ray diffraction (XRD). The two polymers obtained soluble in most polar aprotic solvents even less solvents, which are practical easily accessible solvents. Their thermal determined thermogravimetric analysis (TGA) differential scanning calorimetry (DSC). These showed high resistance decomposition up 490 °C, glass transition temperature (Tg) 180 °C. photophysical UV/Visible absorption. doped then deposited cellulose filaments, an approach that made it possible produce self-supporting conductive composites thanks mechanical properties. topography resulting materials at submicron scales before estimating electronic conductivity gap energy diffuse reflection spectroscopy.

This research work is aimed at green synthesis with sustainability towards the production of copper (Cu)-Based Metal Organic Framework (MOF) and their doping in titanium dioxide (TiO₂) nanoparticles synthesized using a natural reductant stabilizer, Cinnamomum verum (C. verum) bark extract. It an eco-friendly technique because bioactive compounds such as flavonoids polyphenols present C. help reduce stabilize metal ions, thus replacing toxic chemicals. The Cu-doped TiO₂ nanocomposites are found to absorb increased visible light owing reduced bandgap from doping, observed by UV-Vis Diffuse Reflectance Spectroscopy (UV-DRS). scanning electron microscopy energy-dispersive X-ray spectroscopy analysis indicates that distribution Cu matrix uniform, which offers structural stability functional efficacy. Well-diffusion experiments on antimicrobial studies reveal produced this process have excellent activity, especially Staphylococcus aureus. attributed photoinduced generation ROS, can break cell walls interfere microbial metabolism. for Cu-TiO2 nanocomposite totally compliance chemistry principles produces having strong photocatalytic action. These results outline grand potential methods-prepared be used coatings, environmental remediation, much more - opening promising route sustainable nanotechnology development.
