H. Meng et al., Synthesis and electrochemical characterization of a new polymer constituted of alternating carbazole and oxadiazole moieties, SYNTH METAL, 100(3), 1999, pp. 297-301
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
