中文摘要: |
含多个亚苯基作为刚棒,低聚醚作为柔性链的刚-柔 (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。分子自组装需要两个条件:驱动力(非共价键的弱相互作用力)和导向作用(分子在空间的互补性)。刚性嵌段的形状不仅决定了分子排列方向、空间尺寸,而且还影响着驱动力的大小,因此本文综述了以亚苯基为V型刚棒,低聚醚作为柔性链的刚-柔分子自组装行为,并展望了V型刚-柔分子未来的研究方向。 |
英文摘要: |
Rational molecular design can create self-assembled nanostructures through weak intermolecular forces, such as hydrogen bonding, donor-acceptor interactions and reversible ligand-metal interactions. The rod-coil molecules, containing the multi-phenylene as a rod and oligo-ether 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 driving force (weak interaction of non-covalent bonds) and guiding role (complementarity of molecules in space) are necessary when the molecules self-assemble. The shape of a rigid block not only determines the orientation of molecules, space size, but also affects the intensity of the driving force. In this paper, the self-assembling behaviors of V-shaped rod-coil molecules are summarized and the future research trend of this kind of rod-coil molecules is prospected. |
