In the development of functional materials, side chains are traditionally incorporated into the primary chemical structure to induce liquid-crystalline behavior or to enhance solubility for improved processability. However, emerging evidence suggests that side chains play a far more complex role. This study presents a case of a double helical supramolecular structure formed by star-shaped mesogens in the absence of specific interactions.

Article Synopsis
- Self-healing polymers present a new solution to wear and tear in polymer products, addressing damage from mechanical stress and environmental factors.
- A series of high-strength copolymers were developed using acrylamide, acrylic acid, and various metal complexes (Co(II), Ni(II), Cu(II)), and their properties were extensively analyzed through multiple physicochemical techniques.
- Nickel-based metallopolymers showed the highest self-healing efficiency (up to 83%) while retaining impressive tensile strength, demonstrating the potential to enhance mechanical properties through different metal ions.
Multi-responsive polymeric nanocontainers attract significant attention for their potential applications in biotechnology, drug delivery, catalysis, and other fields. By incorporating a liquid-crystalline (LC) mesogenic ligand with an alkyl tail length ranging from 8-12 carbons, ionically linked to the polymer backbone, we generate vesicles with walls significantly thinner than those of conventional polymersomes, approaching the thickness of a lipid bilayer. These LC vesicles, ranging in size from 50-120 nm, are designed to be mechanically robust due to the alignment of the hydrophilic polymer backbone within the plane of the vesicle wall.

Inside the AAO structure, the director vector of the mesophase is oriented parallel to the pore axis due to the confinement effect. The molecular arrangement induced by the spatial confinement within the pores is extended over several microns into the remnant film on the AAO surface.
