摘要： 以9,9-双-(3-R-4-氨基苯基)芴(R=H, CH3, F)和1,4-双-(4'-溴苯酰基)苯为单体, 通过Buchwald-Hartwig交叉偶联反应, 缩聚合成了芴基Cardo型聚亚胺酮(PIKF). 利用MS软件对其分子结构进行模拟, 并通过1H NMR和FTIR等方法进行表征, 结果与目标产物吻合. 利用凝胶渗透色谱(GPC)、示差扫描量热(DSC)和热重(TG)等方法对其物理性能进行测试, 结果表明, 该类聚合物分子量较高(Mw>3.5×104), Cardo结构的存在赋予其较高的玻璃化转变温度(Tg>215 ℃)和良好的热稳定性(5%失重温度T5%>400 ℃); X射线衍射(XRD)结果显示含芴聚亚胺酮为无定形结构, 具有良好的溶解性能. UV-Vis吸收光谱峰值(λmax)为271和369 nm, 最大荧光发射波长分别为491和522 nm.

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.
