Keywords: Macrocyclic ligands / Gels / Metathesis / Dynamic covalent chemistry / Copper A 22-membered cyclic alkene C 1 incorporating an exotopic 1,10-phenanthroline nucleus in the ring skeleton has been synthesized and subjected to ring-opening metathesis polymerization (ROMP) in dilute dichloromethane solution at varying monomer concentrations (c mon ). The resultant libraries of macrocyclic oligomers were used as ligands for the generation of main-chain metal-ligand oligomeric/polymeric

Single Molecule Analysis of Self-Assembly Supramolecular Oligomers in Solution

“…Supramolecular polymers are based on monomeric units which are held together with directional and reversible noncovalent interactions involving as π–π interactions, hydrogen bonding, and hydrophobic and hydrophilic interactions. − These noncovalent forces contribute to creating hierarchical or sophisticated structures, which provide intriguing properties for supramolecular polymers including stimuli-responsiveness and self-healing. , During the formation of supramolecular polymers, monodispersed oligomers play an important role because their preorganized precise structures lead to a well-defined structure–property relationship. , Therefore, studying individual self-assembly oligomers is essential for understanding the assembly properties of individual functional supramolecular polymers. To the best of our knowledge, the traditional methods such as fluorescence spectrum , and NMR spectrum , all provided the bulk information on the oligomers. Few experimental approaches own the ability to determine single supramolecular oligomer in aqueous solution.…”
