Description

Polymer self-assemblies driven by enthalpic interactions, such as hydrogen bonding and electrostatic interactions, exhibit distinct properties compared to those driven by hydrophobic interactions. Carbohydrate–carbohydrate interactions, which are observed in physiological phenomena, also fall under enthalpic interactions. Our group previously reported on self-assemblies of methacrylate-type glycopolymers carrying mannose units in the presence of calcium ions; however, a detailed study of these interactions was lacking. In this work, we investigated the interactions between glycopolymers using the quartz crystal microbalance (QCM) method. Our quantitative analysis revealed that the interactions between the glycopolymers were influenced by the carbohydrate structures in the side chains, the types of divalent metal ions, and the structures of the polymer main chains. Notably, the strongest interaction was observed in the combination of methacrylate-type glycopolymers carrying mannose units and calcium ions, demonstrating their potential as a driving force for polymer self-assembly.
