描述了由动态共价键驱动的三维纯有机笼的前所未有的自分选。首先通过两种三胺和两种二醛的缩合反应合成了四种不同的笼状化合物。当所有成分的混合物被允许反应时，只形成了两个笼子，这表明了高保真的自我识别。通过将非优选的组合与适当的三胺或二醛反应而转化为两种优选的组合中的任一种，进一步探讨了一种三胺对于特定二醛的优选性问题。
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.
