摘要: We present the construction of long-chain water-soluble supramolecular polymers at low monomer concentrations. Naphthalene-based host-enhanced π–π interactions, which possess high binding constants, were used as driving force polymerization. A monomer, DNDAB, with a rigid, bulky 1,4-diazabicyclo[2.2.2]octane-1,4-diium linker was designed. The design structure strongly influenced efficiency in DNDAB effectively eliminates cyclization, promoting formation In contrast, reference containing flexible (DNPDN) only forms oligomers owing to cyclization.
