Abstract: Fluorenyl cardo poly(imino ketone)s (PIKF) were designed and synthesized by reacting 1,4-bis-(4-bromobenzoyl)-benzene and 9,9-bis(3-R-4-aminophenyl)fluorene (R: H, CH3 or F). The structures of the resulting polymers were simulated by Materials Studio(MS) and characterized by FT-IR, 1H NMR spectroscopy and elemental analysis. The thermo and optical properties of PIKF were evaluated. High glass transition temperatures (Tg> 215 ℃) and decomposition temperatures (T5%> 400 ℃) were observed by DSC and TGA, respectively. The UV-vis absorption spectra of polymers exhibited two absorption peaks around 271 nm and 369 nm; The maximum emissive wavelength were 501nm in both PIKF-1 and PIKF-2, and 492nm in PIKF-3. PIKF were amorphous at room temperature. Good solubility of PIKF in ordinary organic solvents such as THF and chloroform was confirmed. These properties of the polymers were related to the cardo structure of the fluorene moiety placed on the main chain.
