Fluorenone-based polyamines, as novel light-emitting polymers, were synthesized by the condensation polymerization of 3,6-dibromo-9-fluorenone with different aromatic diamines by palladiumcatalyzed aryl amination reaction. The structures of the polymers were characterized by means of FT-IR, 1H NMR spectroscopy and elemental analysis. The experimental results show a good agreement with the proposed structures. TGA measurement exhibits that the polymers possess good thermal stabilities with high decomposition temperatures(T5 400 ℃). Due to the photo-induced intramolecular charge-transfer(ICT) of fluorenone-based polyimines, these polymers show significantly strong photonic luminescence in N,Ndimethylacetamide.
