含多个对苯撑作为刚棒,齐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、NMR和MALDI-TOF-MS对其结构进行了表征,利用DSC、POM和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。
Rod-coil molecules containing a plurality of phenylene groups as rigid rods, oligomeric alkyl groups, or alkoxy groups as flexible chains, due to their strong microphase separation and π-π stacking effect, Efficient self-assembly in the bulk and solution. The results show that the shape of rigid rod affects the molecular arrangement, self-assembly properties and microstructure. Therefore, n-type rigid block copolymers with n-type aromatic blocks and all flexible chains as n-type rigid rods The structure of the compound was characterized by IR, NMR and MALDI-TOF-MS. The self-assembly behavior of the compound was characterized by DSC, POM and SAXS. The results show that n-type molecules containing alkyl flexible chains form a bilayer structure in the solid state.
