Abstract
We report herein the synthesis and electrochemical characterization of a no vel copolymer containing an electron rich carbazole moiety and an electron deficient oxadiazole unit-poly[N-(2'-ethylhexyl)-carbazole-3,6-diyl-1 ",3 " ,4 "-oxadiazole-2 ",5 "-diyl] (PCO) PCO can be dissolved in THF, CHCl3, xyl ene, and DMSO. The structure of the polymer is confirmed by FT-IR, NMR and elemental analysis. The optical and electronic properties of the polymer ar e investigated by W-Vis absorption spectroscopy and photoluminescence spec troscopy as well as cyclic voltammetry. The results show that the polymer f ilms emit greenish-blue Light (lambda(max) 485 nm) upon UV excitation. Both p-doping and n-doping processes are observed in cyclic voltammetric invest igation. A comparison between the properties of polycarbazole and polycarba zole-oxadiazole has been presented. (C) 1999 Elsevier Science S.A. All righ ts reserved.
