Controlling the Assembly of Ureido‐Pyrimidinone Supramolecular Monomers by Tuning the Hydrophilic‐Hydrophobic Balance

open access: yesJournal of Polymer Science, EarlyView.
In this study, the self‐assembly behavior of water‐compatible UPy‐based supramolecular monomers with varying hydrophilic‐hydrophobic balances is systematically investigated. Experimental and computational analyses reveal that the molecular monomer design is pivotal in steering the self‐assembly properties, highlighting the role of alkyl‐urea spacers in
