説明:

Recently, vibrational strong coupling (VSC) has emerged as a new tool for manipulating specific intermolecular interactions. Although VSC shows promise for controlling molecular assembly, it has not yet to demonstrate the capability to open a pathway for creating structures that are inaccessible by conventional assembly methods. Here, we used VSC to control the transformation process of a naphthalenediimide supramolecular polymer induced by a click reaction. The supramolecular polymers with reactive ethynyl groups undergo a transformation from long fibers to thick fibers upon induction by an amino-yne click reaction in the absence of VSC. Applying VSC to the C–H stretch uniquely altered the morphological transformation process, leading to the formation of metastable toroids instead of thick fibers. These findings link VSC-induced modulation of intermolecular interactions to structural outcomes, establishing VSC as a tool for manipulating molecular assembly beyond traditional assembly methods.
