“…Interestingly, a relevant design of the abiotic polymer structure enables the editing of encoded information by the light trigger . Besides data storage, such macromolecules have been used in catalysis, , drug delivery, − sensing, ,− selective binding, , molecular transport, , or as peptidomimetic foldamers. , The biological environment, where natural macromolecules perform sophisticated functions, is chiral. Therefore, the stereochemistry of macromolecules should be an essential parameter for their function.…”

The development of precision polymer synthesis has facilitated access to a diverse library of abiotic structures wherein chiral monomers are positioned at specific locations within macromolecular chains. These structures are anticipated to exhibit folding characteristics similar to those of biotic macromolecules and possess comparable functionalities. However, the extensive sequence space and numerous variables make selecting a sequence with the desired function challenging. Therefore, revealing sequence− function dependencies and developing practical tools are necessary to analyze their conformations and molecular interactions. In this study, we investigate the effect of stereochemistry, which dictates the spatial location of backbone and pendant groups, on the interaction between sequence-defined oligourethanes and bisphenol A ligands. Various methods are explored to analyze the receptor-like properties of model oligomers and the ligand. The accuracy of molecular dynamics simulations and experimental techniques is assessed to uncover the impact of discrete changes in stereochemical arrangements on the structures of the resulting complexes and their binding strengths. Detailed computational investigations providing atomistic details show that the formed complexes demonstrate significant structural diversity depending on the sequence of stereocenters, thus affecting the oligomer−ligand binding strength. Among the tested techniques, the fluorescence spectroscopy data, fitted to the Stern−Volmer equation, are consistently aligned with the calculations, thus validating the developed simulation methodology. The developed methodology opens a way to engineer the structure of sequence-defined oligomers with receptor-like functionality to explore their practical applications, e.g., as sensory materials.

“…In a single modification, the heterocyclic carbonyl undergoes chemo- and regioselective amidation, while in the additional presence of a Michael acceptor (e.g., maleimide), a double modification takes place (ring opening, followed by a thiol–X reaction). , The unique reactivity of TLs can be introduced through the commercially available homocysteine thiolactone (HCTL), which can be easily modified through the amine in the α-position (Figure ). Hence, it has been extensively used for postpolymerization modifications, − toward sequence-defined and functional polymers, − surfaces, , hydrogels, , and bioconjugate materials. − …”
