From Frustration to Order: Role of Fluid-Fluid Interfaces in Precision Assembly of Nanoparticles.

Fluid-fluid interfaces are an attractive platform for self-assembling nanoparticles into low-dimensional materials. In this Perspective, we review recent developments in the use of interfaces to direct the assembly of spherical and anisotropic nanoparticles into diverse and sophisticated architectures. We illustrate how nanoparticle clusters, strings, networks, superlattices, chiral lattices, and quasicrystals can be self-assembled by harnessing the frustration between interfacial and interparticle forces.

The self-assembly of colloidal nanocrystals typically leads to the formation of highly symmetric superlattices, while chiral symmetry breaking within these structures remains rare. Here, we present a universal approach for achieving chiral symmetry breaking within self-assembled nanocrystal superlattices through the incorporation of nanowires and shear force. The networked film, composed of highly flexible nanowires that are only a few nanometers in diameter and bound by weak van der Waals interactions, can be manipulated to stretch and rotate, resulting in a controlled chiral pattern with a specified handedness.

Crystalline solids typically show robust long-range structural ordering, vital for their remarkable electronic properties and use in functional electronics, albeit with limited customization space. By contrast, synthetic molecular systems provide highly tunable structural topologies and versatile functionalities but are often too delicate for scalable electronic integration. Combining these two systems could harness the strengths of both, yet realizing this integration is challenging owing to distinct chemical bonding structures and processing conditions.

Studies of moiré systems have explained the effect of superlattice modulations on their properties, demonstrating new correlated phases. However, most experimental studies have focused on a few layers in two-dimensional systems. Extending twistronics to three dimensions, in which the twist extends into the third dimension, remains underexplored because of the challenges associated with the manual stacking of layers.
