The syntheses of novel copolymers containing indolo[3,2-b]carbazole (INC) moiety were carried out, and the effect of INC content on the physical properties were investigated. All the copolymers were glassy and the decomposition temperatures were nearly 400 °C. It was found that the photoluminescence intensities of the copolymer films decreased with the increase of INC content, which would be caused by the concentration quenching by the intermolecular interaction between INC components. The copolymer with low content of INC moiety exhibited the high emission property and good film-forming ability.
