A heteroditopic monomer (H) comprised of ureidopyrimidinone (UPy) group and benzo-21-crown-7 motif and a homoditopic monomer (G) containing two dialkylammonium salt units have been successfully prepared. The functional groups both in H and G are linked together by a short spacer. Through quadruple hydrogen bonds, H can self-assemble into dimers, which are capable of complexing with G via host-guest interaction to form linear supramolecular copolymers. The supramolecular copolymers were fully characterized by various techniques, such as concentration-dependent 1H NMR, viscosity measurements, and scanning electron microscope (SEM). The results will inspire the orthogonal construction of supramolecular polymers for smart materials in more fields.
