Summary
Oxidative polymerization of 3,6-diethynyl-9-hexylcarbazole with oxygen in the presence of copper complex affords soluble poly(9-hexylcarbazole-3,6-diylbutadiynylene) in good yield. Irradiation with UV-vis. light and annealing under nitrogen lead to photochemical and thermal cross-linking and insolubilization of the polymer film.
