摘要:

通过Sonogashira偶联等反应, 合成了2种含蒽的三嵌段十字型化合物1和2; 通过1H NMR和基质辅助激光解吸电离时间飞行质谱(MALDI-TOF MS)对其结构进行了表征. 利用差示扫描量热法(DSC)、 偏光显微镜(POM)及小角X射线散射实验(SAXS)对2种化合物的本体自组装行为进行了研究. 结果表明, 在本体状态下, 连接聚环氧乙烷(PEO)作为柔性链的化合物在液晶中间相自组装成倾斜柱状相和向列相, 以烷基链为柔性链的化合物未形成液晶相, 在固态相是层状结构.

Abstract:

Rod-coil molecules, consisting of a flexible and a rigid block, have a strong tendency to self-organize into a various supramolecular nanostructures in the bulk state. Coil-rod-coil triblock cruciform compounds 1 and 2 incorporating anthracene unit were synthesized through Sonogashira coupling reaction. Molecular structures of these compounds were characterized by 1H NMR and MALDI-TOF mass spectroscopy. The self-assembling behaviors of these molecules were investigated by means of differential scanning calorimetry(DSC), thermal polarized optical microscopy(POM), small-angle and wide-angle X-ray scattering(SAXS and WAXS) at the bulk state. In liquid crystalline mesophase, compounds 1 connecting with poly(ethylene oxide)(PEO) as flexible chains self-assembles into oblique columnar phase(Colo) and nematic phase, while compound 2 containing alkyl flexible chain self-assembles into lamellar structure(L) in the solid state, and has not shown liquid crystalline phase.

Key words: Rod-coil molecule, Self-assembly, Anthracene unit, Cruciform
