  Controlling the self-assembly of cationic bolaamphiphiles: counterion-directed transitions from 0D/1D to exclusively 2D planar structures

  摘要：

  阳离子球状两亲分子的自组装通常被报道形成一维（1D）或零维（0D）结构，而非二维（2D）结构。在这里，我们发现了一种简单的反离子导向结构转换方法可用于这种两亲分子。通过简单地将反离子更改为磺酰基，阳离子球状两亲分子自组装形成的0D/1D结构可以转变为2D平面结构。单晶结构和变温核磁共振研究表明，磺酰基反离子与阳离子头基之间的强结合推动了2D平面结构的形成。我们高度期待这种方法可以作为一种简单的方法来控制嵌入的共轭核心在球状两亲分子中的堆叠，从而调节此类组装体的光电性质和功能。
