Based on the 9,9‐di(4‐anilinyl)fluorene, structurally different fluorene‐polyimino ketones have been obtained by the Buchwald‐Hartwig cross coupling reaction. Their structure and performance have been characterized by FT‐IR, 1 H NMR, UV‐vis and thermal analysis. The results show an agreement with the proposed structure, which possesses high glass transition temperature ( T g >250 °C) and good thermal stability with high decomposition temperatures in nitrogen atmosphere ( T D >520 °C). Additionally, the polymers synthesized showed good solubility, which can be dissolved in common organic solvent CHCl 3 at room temperature.
