dc.description.abstractThis paper presents the design of a novel Schiff base, 2,2'-{[1,2-di(pyridin-2-yl)ethane-1,2-diylidene]bis(azanylylidene)}diphenol (2,2’-DBD), and its oligophenol, Oligo-(2,2'-{[1,2-di(pyridin-2-yl)ethane-1,2-diylidene]bis(azanylylidene)}diphenol) O(2,2’-DBD), synthesized with NaOCl and O2 oxidants by oxidative polycondensation reaction in aqueous alkaline media. The effects of oxidant type, polymerization temperature, and time on oligomer yield were determined. Characterization of the structures of the synthesized (2,2’-DBD) and O(2,2’-DBD) were done by UV-Vis, FTIR and1HNMR techniques. Also, thermal degradations of the monomer and oligomer were investigated TG-DTG analysis and it was determined that the oligomer thermally stable up to 1200 °C. Additionally, electrical conductivity of the oligomer was improved by doping with iodine at 20 °C and the conductivity of the oligomer reached to 9x10-4 S/cm by increasing 107 at the end of the 48 h doping time fold according to its undoped form. © 2018, Turkish Chemical Society.
