| 中文摘要: |
| 含多个对苯撑作为刚棒,低聚烷基或烷氧基作为柔性链的刚棒-线团(rod-coil)分子,由于具有很强的微相分离和π-π堆积作用,可以在本体和溶液中产生有效的自组装。研究表明刚棒嵌段的形状影响着分子排列的方式、自组装性能和微结构,因此本文设计了n型芳香嵌段、柔性链全部为烷基的n型刚棒-线团分子,通过红外光谱法(IR),核磁共振波谱法(NMR)和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MASS)对其结构进行了表征,利用差示扫描量热法(DSC)、热台偏光显微镜(POM)和小角X-射线散射实验(SAXS)对此化合物的自组装行为进行了研究。结果表明含烷基柔性链的n型分子在固态时能形成双分子的层状结构。 |
| 英文摘要: |
| The rod-coil molecules, containing the multi-paraphenylene as a rod and oligo alkyl and alkoxyl group as a coil chain, are able to self-assemble into various supramolecular nanostructures in bulk and aqueous solution, caused by strong microphase separation of rod and coil segments and π-π stacking of aromatic rod segments interaction. The shapes of the rod block can dramatically influence on the fashion of molecular arrangement, self-organizing property and micro-structure of rod-coil molecular system. The n-shaped rod-coil molecule containing alkyl chains is successfully synthesized and characterized by IR, NMR and MALDI-TOS-MASS. The self-assembly behavior is studied using differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and small angle X-ray scattering (SAXS) experiment. The results show that n-shaped rod-coil molecule containing octadecyl flexible chains can self-assemble into a dimolecular layer structure at the solid state. |
