We report the efficient condensation of imine-based macrocycles from dialdehyde A and aliphatic diamines Bn in pure water. Within the libraries, we identified a family of homologous amphiphilic [2]catenanes, whose self-assembly is primarily driven by the hydrophobic effect. The length and odd-even character of the diamine alkyl linker dictate both the yield and the conformation of the [2]catenanes, whose particular thermodynamic stability further shifts the overall equilibrium in favour of imine condensation. These findings highlight the role played by solvophobic effects in the self-assembly of complex architectures.

水中的亚胺基[2]环烷†

我们报道了二醛A和脂肪族二胺B n在纯水中有效缩合亚胺基大环化合物。在文库中,我们鉴定了一系列同源两亲性[2]链烷,其自组装主要由疏水效应驱动。二胺烷基连接体的长度和奇偶特征决定了[2]环烷的产率和构象,其特殊的热力学稳定性进一步改变了总体平衡,有利于亚胺缩合。这些发现强调了疏溶剂效应在复杂结构的自组装中所发挥的作用。
