Abstract

1,8-Dibromocarbazole was employed to construct zigzagged conformation via the Suzuki-type cross-coupling polycondensation. Model copolymer, poly(Czl,8-co-F), showed deep-blue 420nm emission in thin film. Air-annealing experiments for 18 h at 200°C with a low green index (/GIWBIUC) of 0-38 indicated the introduction of nonlinear zigzag-shaped 1,8-dibromocarbazole building blocks into polyfluorene (PF) clearly improved spectral stabilities.
