The preparation of dynamic imine macrocycles and supramolecular polymers is combined into a single step to form supramolecular polymers (SPs). 1,4-Diazabicyclo[2.2.2]octane (DABCO) derived quaternary ammonium salts induce aldehyde and amine building blocks to covalently form imine macrocycles. Multiple noncovalent interactions between hosts (i.e., imine macrocycle) and guests (i.e., DABCO) act as driving forces. Thus, for the first time, dynamic imine macrocyclic supramolecular polymers (DIMPs) have been achieved through the synchronized self-assembly of dynamic covalent bond formed imine macrocycles and noncovalent interactions of hosts-guests.
动态亚胺大环化合物和超分子聚合物的制备合并为一步，以形成超分子聚合物（SPs）。1,4-二氮杂双环[2.2.2]辛烷（DABCO）衍生的季铵盐诱导醛和胺构建块共价形成亚胺大环化合物。主体（即亚胺大环化合物）和客体（即DABCO）之间的多种非共价相互作用充当驱动力。因此，首次通过动态共价键形成的亚胺大环化合物的同步自组装和主客体的非共价相互作用实现了动态亚胺大环超分子聚合物（DIMPs）。
