This paper
presents 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 in aqueous alkaline medium by oxidative polycondensation reaction. 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 and 1HNMR
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.
