Contrary to the popular belief that multicomponent assembly systems will theoretically co-assemble under the same type of driving forces, two distinct assembly modes from a system composed of two chemically similar supramolecules were demonstrated in this work. Although with exactly the same driving forces, molecule-level self-sorting unexpectedly occurred in this two-component system made of polyhedral oligomeric silsesquioxane (POSS) core-based supramolecules with one and eight lysine derivative arms. From the experiments, it was concluded that instead of driving force types, driving force counterpoise plays a vital role here, which we called “identity card hypothesis”. The hypothesis suggests that two highly similar components show high affinity for the same molecules through the differentiated “identity card”-like balance of driving forces induced by the difference in the molecular spatial shape, which has never been reported before.

驱动力平衡-自分选多组分组装系统中超分子的“身份证”

与普遍认为多组分组装系统在理论上将在相同类型的驱动力下共同组装的普遍看法相反,这项工作证明了与由两个化学相似的超分子组成的系统不同的两种组装模式。尽管具有完全相同的驱动力,但是在这种由多面体低聚倍半硅氧烷(POSS)核基超分子与一个和八个赖氨酸衍生臂组成的两组分系统中,分子级自选却意外发生。从实验得出的结论是,驱动力平衡在这里起着至关重要的作用,而不是驱动力类型,我们称之为“身份证假说”。
