Unprecedented self-sorting of three-dimensional purely organic cages driven by dynamic covalent bonds is described. Four different cages were first synthesized by condensation of two triamines and two dialdehydes separately. When a mixture of all the components was allowed to react, only two cages were formed, which suggests a high-fidelity self-recognition. The issue of the preference of one triamine for a particular dialdehyde was further probed by transforming a non-preferred combination to either of the two preferred combinations by reacting it with the appropriate triamine or dialdehyde.
本文描述了一种前所未有的由动态共价键驱动的三维纯有机笼的自组装。首先通过缩合两种三胺和两种二醛分别合成了四个不同的笼子。当允许所有成分的混合物反应时，只形成了两种笼子，这表明了高度保真的自识别。通过将不优选的组合与适当的三胺或二醛反应转化为两种优选组合之一，进一步探究了一种三胺对特定二醛的偏好问题。
