Synthesis of dynamic imine macrocyclic supramolecular polymers via synchronized self-assembly based on dynamic covalent bonds and noncovalent interactions

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.
