We show that the use of reversibly connected trialdehyde cores and diamine hydrophilic/hydrophobic connectors may generate libraries of dynameric frameworks of variable composition. The dynamic reversible imine- and trans-imination reactions induce the progressive segregation of libraries consisting of homo- and heterodynameric frameworks through the constitutional selection and successive precipitation of low-soluble hydrophobic films and hydrophilic/hydrophobic core–shell particles. This “precipitation-driven segregation” results in the formation of membrane with unique asymmetric morpholgy. Systematic compositional changes of dynamers, segregating solvents, and casting surfaces were correlated with the emerged membrane structure, and NMR/transmission electron microscopy–energy-dispersive X-ray characterizations mostly supported their hypothesis.

对名框架图书馆宪法相变选择的机理分析
我们表明使用可逆连接的三醛核心和二胺亲水/疏水连接器的使用可能会生成组成可变的dynameric框架的库。动态可逆的亚胺和氨基转移反应通过组成选择和连续沉淀低溶性疏水膜和亲水/疏水核-壳颗粒，诱导由同型和异型骨架组成的文库的逐步分离。这种“沉淀驱动的分离”导致形成具有独特的不对称形态的膜。dynamers，分离溶剂和铸件表面的系统组成变化与出现的膜结构相关，并且NMR /透射电子显微镜–能量色散X射线表征主要支持了它们的假说。
