The oligo(azomethine ether)s were synthesized via polycondensation of alkyl diamines with aromatic dialdehydes. Two series of dialdehydes,namely 2,2’-[l,2-phenylenebis(methyleneoxy)]dibenzaldehyde[2,2’-l,2-(PBMODB)]and 2,2’- [l,4-phenylenebis(methyleneoxy)]dibenzaldehyde[2,2’-l,4-(PBMODB)]were prepared from the condensation reactions of salicylaldehyde with o-xylenedibromide and /7-xylenedibromide,respectively.The structures of dialdehydes and oligomers were determined by FT-IR,’ H-NMR and 13C-NMR.The thermal analyses of oligomers were conducted by DSC and TG/DTA techniques,respectively.Size exclusion chromatography(SEC) technique was also used to determine molecular weights and molecular weight distributions of oligomers.Electrochemical properties of the synthesized products were investigated.
