Polymers containing alkoxy-substituted spirobifluorene have been prepared from nickel(0)-mediated coupling or palladium-catalyzed Suzuki coupling. The polymers were characterized using various spectroscopies, such as 1 H-NMR, FT-IR, and elemental analysis. The high glass transition temperature and high decomposition temperature suggested that the resulting polymers possessed a high thermal stability. The obtained polymers possessed weight average molecular weight of 4500 -33,000 with polydispersity index of 1.1-1.9 and good solubility. The low onsets of the oxidation potential suggested that the polymers containing alkoxy substituted spirobifluorene possessed a good hole injection property. The photoluminescence and electroluminescence of the polymers containing alkoxy substituted spirobifluorene showed stable blue color by suppressing the excimer formation due to intermolecular interaction.
