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 polymerization process are combined into a single step to form supramolecular polymers (SPs). 1,4-diazabicyclo[2.2.2]octane (DABCO) derived quaternary ammonium salts induce the 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 the driving force. Thus, for the first time, dynamic imine macrocyclic supramolecular polymers (DIMPs) have been achieved by synchronized self-assembly of dynamic covalent formed imine macrocycles and noncovalent interactions of hosts – guests.
