Supramolecular Chiral 2D Materials and Emerging Functions

Abstract: Chiral materials are widely applied in various fields such as enantiomeric separation, asymmetric catalysis, and chiroptical effects, providing stereospecific conditions and environments. Supramolecular concepts to create the chiral materials can provide an insight for emerging chiro-optical properties due to their well-defined scaffolds and the precise functionalization of the surfaces or skeletons. Among the various supramolecular chiral structures, 2D chiral sheet structures are particularly interesting mat… Show more

“…Stacks of flat objects twisted in one direction overcome this problem due to mirror symmetry breaking, as exemplified in the twist stacking of bilayer graphene . Symmetry breaking by twisting can be applied to macrocycle stacks to generate chiral pores . For example, when facing macrocycle dimers are twisted with respect to each other in one direction, the breaking of mirror symmetry induces the formation of chiral pores .…”

“…[17] Symmetry breaking by twisting can be applied to macrocycle stacks to generate chiral pores. [18] For example, when facing macrocycle dimers are twisted with respect to each other in one direction, the breaking of mirror symmetry induces the formation of chiral pores. [19] The twisted dimeric stacks with a chiral interior laterally associate to form single-layered chiral sheet structures, while layer stacks are prohibited because the 2D aromatic surfaces are covered by the flexible chains.…”

“…Among diverse self‐assembling modules, aromatic amphiphiles can serve as remarkable candidates for the creation of well‐defined supramolecular 2D structures owing to their rigidity and the π–π stacking of aromatic groups. [ 15–17 ] In self‐assembled 2D structures composed of aromatic amphiphiles, the rigid aromatic segments surrounded by hydrophilic flexible chains can form relatively stable noncovalent interactions in a preferred direction. [ 18 ] Besides, the packing arrangements of aromatic segments can reversibly transform into a different equilibrium state when subjected to subtle environmental changes, demonstrating a distinct adaptive capability of dynamic shape alterations.…”
