Fluorene-based poly(imino ketone) with fluorine atoms in the side chains (PIKF-F), as an intelligent, high-performance polymer, was synthesized by the reaction of 4,4′-dibromobenzophenone and 9,9-bis(3-F-4-aminophenyl) fluorene via a palladium catalyzed C-N cross-coupling reaction. Its structure was characterized by means of FT-IR and ¹H NMR spectroscopy. The results showed a good agreement with the proposed structure. The molecular weights of the PIKF-F were measured by GPC (calibrated by polystyrene standards). The M_n and M_w values were 64,800 and 153,300, respectively. Thermogravimetric analysis and differential scanning calorimetry measurements showed that the polymer possessed good thermal stability with a high 10% decomposition temperature (450 °C) and a high glass transition temperature (T_g = 250 °C). The PIKF-F exhibited UV (ultra violet) absorption bands at 340–370 nm in NMP solution, while the fluorescence spectra showed maximum emission of PIKF-F at 498 nm in NMP solution. Both optical properties indicate the PIKF-F is of potential use as an organic photoelectric material. Additionally, due to its special conjugated system and the intramolecular hydrogen bonding (N–H···F), it was endowed with significantly strong photonic luminescence and the change of fluorescent intensity was reversible as the temperature was changed.

通过4,4'-二溴二苯甲酮与9,9-双（3）的反应合成了侧链含氟原子的芴基聚亚氨基酮（PIKF-F），它是一种智能的高性能聚合物。 -F-4-氨基苯基）芴通过钯催化的CN交叉偶联反应。其结构通过FT-IR和¹ H NMR光谱表征。结果表明，该结构与拟议的结构吻合良好。PIKF-F的分子量通过GPC（通过聚苯乙烯标准物校准）测量。在中号_ñ和中号_{w ^}值分别为64,800和153,300。热重分析和差示扫描量热法测量表明，该聚合物具有良好的热稳定性，具有高的10％分解温度（450°C）和高的玻璃化转变温度（T _g = 250°C）。在NMP溶液中，PIKF-F在340–370 nm处显示UV（超紫）吸收带，而荧光光谱显示在NMP溶液中，在498 nm处PIKF-F的最大发射。两种光学性能均表明PIKF-F可用作有机光电材料。此外，由于其特殊的共轭体系和分子内氢键（N–H···F），具有明显强的光子发光，并且随着温度的变化，荧光强度的变化是可逆的。
