Synthesis and characterization with oxidative polycondensation reaction some of the aromatic compounds

Schiff base compounds were synthesized by condensation reaction of 2-aminophenol and 4-aminophenol compounds with 4-isopropenylclohexyl-1-en-1-carbaldehiyde and 3,5-di-tert-butyl-2-hydroxybenzaldehyde. Polyimines were synthesized from Schiff bases by oxidative polycondensation. Sodium hypochlorite (NaOCl) and air were used as oxidant. Polymers were synthesized in THF medium at 70°C. Solubility tests of all the synthesized Schiff bases and polymers were performed in acetone, THF, chloroform, acetonitrile, methanol, etylacetate, n-hexane and DMSO. The structures of all compounds were determined by FT-IR, UV-vis, 1H-NMR, 13C-NMR and CV techniques. In addition, thermal properties of Schiff bases and polymers were characterized with TGA, DTG, DTA and DSC analysis. Photoluminesans (PL) properties of the synthesized compounds were determined in solution forms in DMSO. The number-average molecular weight (Mn), weight average molecular weight (Mw) and polydispersity index (PDI) values of the synthesized compounds were determined by the size exclusion chromatography (SEC).
