The programmed self-assembly of patchy nanoparticles (NPs) through a bottom-up approach is an efficient strategy for producing highly organized materials with predetermined architecture. Herein, we report the preparation di- and trivalent silica NPs polystyrene (PS)/poly(4-vinylbenzyl azide) (PVBA) patches assemble them in THF mixture by lowering solvent quality. Silica–PS/PVBA colloidal hybrid clusters were synthesized seeded growth emulsion copolymerization styrene 4-vinylbenzyl azide (VBA) varying ratios.

Published: March 3, 2023

Abstract Gyroid structures are of extensive interest because they provide a rich platform for chiroptics as well topological photonics. While the double‐gyroid morphology bicontinuous structure is not uncommon in self‐assembled soft materials, direct self‐assembly single‐network gyroids has proven elusive. Here, an enantiomorphic pair single‐gyroid crystals comprising colloidal spheres presented, and two distinct routes demonstrated programmed each single gyroid enantiomorph from rationally designed patchy spheres. The designer spheres, which closely hew to their synthetic feasibility, chiral, having either staggered rectangular patches at opposite poles or four circular arranged well‐defined geometry. gyroid, its inverse structure, shown support wide complete photonic bandgap addition exhibiting chiroptical properties, making them attractive chiral crystals. versatility this bottom‐up devised here silico, robustness design space together make strong case supersede diamond, target self‐assembly, quest operating optical frequencies.

Disordered structures with short-range correlation exhibit unique photonic or thermal properties, often arising from the self-assembly of monodisperse microspheres. Colloidal clusters, aggregates a defined number microspheres, have anisotropic shapes and offer approach to tailor compared traditional isotropic However, this potential remains largely unexplored. To end, we prepared triangular tetrahedral colloidal clusters coassemble them polystyrene microspheres into both monolayers thick films (∼10 μm) over 5 mm × areas. Through combining scanning electron microscopy images laser scattering measurements, show that increasing cluster concentration 0% 40% increases disorder in thin films. Beyond 40%, order plateaus, while it but decreases The distinct roles new insights design correlated disordered materials for novel applications.
