    through Dislocation of Hydrogen-Bonded π-Rosettes'

## Description

- description: In this work, we expound upon the manifestation of two supramolecular
    polymer polymorphs formed from a large discotic supramolecular monomer (rosette),
    which consists of six hydrogen-bonded molecules with an extended π-conjugated
    core. These polymorphs are generated in mixtures of chloroform and methylcyclohexane,
    attributable to distinctly differ-ent disc stacking arrangements. These arrangements
    can be classified as H-type and J-type stacking predicated on their distinctive
    photophysical properties. The H-type stacking, delineated by minimal rosette displacement,
    results in a twisted helix structure. Conversely, the J-type stacking, characterized
    by significant rosette displacement, induces inherent curvature in the supramolecular
    fiber, thereby culminating in a hollow helical coil (helicoid). While both polymorphs
    exhibit bistability in nonpolar solvent compositions, the H-type stacking attains
    stability purely in a kinetic sense within a polar solvent composition and undergoes
    conversion into the J-type stacking through a dislocation of stacked rosettes.
    This occurs without the dissociation and nucleation of monomers, leading to an
    unprece-dented helicoidal folding of supramolecular polymers. The direct helicoidal
    folding of supramolecular polymer fibers enables the trans-formation of extraordinarily
    long twisted helices into helicoids over the mesoscopic regime. Concurrently,
    distinct cohesive behaviors manifest in conjunction with the structural conversion
    observed within these extended supramolecular polymer materials. their ag-glomeration
    behaviors. Our findings not only augment our understanding of supramolecular polymer
    polymorphism, but they also highlight a distinctive method for achieving helicoidal
    folding in supramolecular polymers.
