Expanding quasiperiodicity in soft matter: Supramolecular decagonal quasicrystals by binary giant molecule blends

Yuchu Liu et al.

Summary: Quasiperiodic structures in metal alloys have been found to be related to the icosahedral order in the melt. Among various phases observed in intermetallics, decagonal quasicrystal (DQC) structures have been identified in many glass-forming alloys but are still inaccessible in bulk-state condensed soft matters. By annealing a mixture of two giant molecules, a binary system can assemble into an axial DQC superlattice, which is comprehensively identified with meso-atomic accuracy. Analysis shows that the DQC superlattice is composed of mesoatoms with an unusually broad volume distribution. The interplays of submesoatomic (molecular) and mesoatomic (supramolecular) local packings are found to play a crucial role in the formation of the metastable DQC superlattice and its transition to dodecagonal quasicrystal and Frank-Kasper sigma superlattices.

Native conjugation between proteins and [60]fullerene derivatives using SpyTag as a reactive handle

Guangzhong Yin et al.

Summary: The study demonstrates facile conjugation between proteins and water-soluble [60]fullerene derivatives (DC60) under native conditions using SpyTag. The bioconjugation was confirmed by MALDI-TOF MS spectra and SDS-PAGE analysis, while TEM and UV-vis spectroscopic study revealed the alteration in optical performance induced by DC60 and aggregation of target proteins. This method provides a general and robust approach for modifying proteins with C-60 derivatives.

Macroscopic Regulation of Hierarchical Nanostructures in Liquid-crystalline Block Copolymers towards Functional Materials

Feng Cai et al.

Summary: Liquid-crystalline block copolymers containing photoresponsive mesogens have great potential for novel applications in photonics and nanotechnology, thanks to their hierarchically-assembled structures and microphase separation properties. The periodically ordered nanostructures in bulk film of these copolymers can improve physical properties and enable advanced functional applications through supramolecular cooperative motion. Various micro/nano-patterned structures have been successfully fabricated through light manipulation of these copolymers, showcasing good reproducibility and mass production capability. Recent developments in synthesis and polymerization techniques have led to the design of diverse azobenzene-containing LCBCs, resulting in the creation of a wide variety of novel functions.

Fabrication of High χ-Low N Block Copolymers with Thermally Stable Sub-5 nm Microdomains Using Polyzwitterion as a Constituent Block

Shi-Peng Ding et al.

Summary: In this study, zwitterionic poly(4-vinylpyridine) propane-1-sulfonate (PVPS) was used to construct high chi-low N block copolymers (BCPs) with different neutral polymers, forming lamellar structures with sub-5 nm microdomains. The electrostatic interaction in polyzwitterion led to relatively high Flory-Huggins parameters (chi) between PVPS and most neutral polymers, facilitating efficient fabrication of BCPs. The sub-5 nm structures in PVPS-containing BCPs showed high thermal stability with minimal fluctuation in domain spacings upon heating.

Crystallization Induced Self-Assembly: A Strategy to Achieve Ultra-Small Domain Sizes

Ming-Sheng Ji et al.

Summary: This study demonstrates the preparation and self-assembly of giant molecules composed of vinyl polyhedral oligomeric silsesquioxane (VPOSS) tethered with monodispersed oligo(L-lactide) chains, achieving ultra-small domain sizes of phase-separated lamellar morphology. Small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) results show that the strong tendency and fast kinetics for crystallization of VPOSS moieties drive the formation of ultra-small domain sizes. Upon pyrolysis at high temperature, ultra-thin two-dimensional nano-silica sheets can be obtained.

Phase Behaviors of Multi-tailed B2AB2-Type Regio-isomeric Giant Surfactants at the Columnar-Spherical Boundary

Yu Shao et al.

Summary: The precision synthesis and phase behaviors of multi-tailed B(2)AB(2)-type regio-isomeric giant surfactants were successfully achieved in this study. The slight structural disparities in different regio-isomeric surfactants not only led to unconventional phase formation in single-component macromolecules, but also resulted in dynamic and rich phase behaviors in these macromolecular assemblies.

Phase Behaviors of Giant Surfactants with Different Numbers of Fluorinated Polyhedral Oligomeric Silsesquioxane Heads and One Poly(ethylene oxide) Tail at the Air-Water Interface

Xian Xu et al.

Summary: This study investigates the phase behaviors of giant surfactants with different numbers of aryltrifluorovinyl ether-functionalized polyhedral oligomeric silsesquioxane (FVPOSS) heads at the air-water interface. The interfacial behaviors greatly change with an increase in the number of FVPOSS heads, showing more phase transitions and morphological evolution. Molecular mechanisms are proposed to explain the phase transitions at the interface.

Towards achieving a large-area and defec t-free nano-line pattern via controlled self-assembly by sequential annealing

Tao Wen et al.

Summary: Utilizing the controlled self-assembling of a giant surfactant, a bottom-up method for constructing line gratings with sub-10 nm resolution has been developed. The process involves solvent vapor annealing to self-assemble the giant surfactant into lamellae structures, followed by thermal annealing to promote long-range ordering. This simple and economic approach results in highly oriented and defect-free sub-10 nm line patterns on a large scale.

Effect of branching architecture on the self-assembly of symmetric ABC-type block terpolymers

Luyang Li et al.

Summary: It is well known that phase boundaries of AB-type block copolymers can be deflected by designing asymmetric architectures. A symmetric ABC-type pentablock terpolymer was designed by branching B-blocks, showing control over the self-assembly behaviors through the length ratio of the middle B-block. Interestingly, a transition from spherical phase to gyroid phase without the cylindrical phase was observed, attributed to three complex effects including the branching effect, packing frustration, and bridging middle B-block.

Effect of crystallization of the polyhedral oligomeric silsesquioxane block on self-assembly in hybrid organic-inorganic block copolymers with salt

Gurmukh K. Sethi et al.

Summary: The study explores the influence of POSS block crystallinity on the self-assembly of polymers through DSC and X-ray scattering. Regardless of the copolymer type, POSS blocks organize into rhombohedral crystals in the polymer/salt mixtures, favoring morphologies with flat interfaces. The findings suggest that semicrystalline polymer/salt mixtures tend to form lamellar structures despite the asymmetric nature of the copolymers.
