Summary: This paper reports the observation of broad voltage-tunable electroluminescence (EL) in colloidal type-II InP/ZnS quantum-dot-seeded CdS tetrapod (TP) LEDs. The EL color can be tuned from red to bluish white by varying the red and blue emission intensities from type-II interfaces and arms, respectively. External electric field enhancement of color tuning in type-II TPs is proven by a capacitor device. This study provides a novel method to realize voltage-tunable EL colors with potential in display and micro-optoelectronic applications.

Summary: Covalent organic frameworks (COFs) exist in diverse forms in bulk, with distinct nanostructures impacting the properties of their bulk counterparts, yet the focus remains primarily on the covalent reticular structure, neglecting the chemistry of COFs at the nano regime. The synthetic design of COFs can be extended beyond the molecular framework to the nano-meso-macroscale hierarchy, showcasing the importance of hierarchical assembly in COF nanosynthesis.

Summary: Recently, the combination of seed-mediated growth and thiolated chiral molecule-guided growth has shown promise in obtaining chiral plasmonic nanostructures. In this study, the roles of non-chiral cationic surfactants in helical growth were investigated. The counter anion and hydrocarbon chain length of the surfactants were found to greatly affect the formation of helical shells, allowing for surfactant-modulated conversion between layer growth and island growth. Optimized growth conditions resulted in a significant plasmonic circular dichroism (PCD) response, demonstrating the potential of nanochemical synthesis in fabricating chiral plasmonic nanostructures with small structural sizes.

Summary: Multicomponent supramolecular systems can achieve different properties and new behaviors compared to single-component systems. In this study, a two-component system is used to modify the assembly of the gelling component, resulting in co-assembled structures that cannot be formed by the gelling component alone. The systems are characterized at multiple length scales, and the addition of a second component enhances the mechanical properties of the multicomponent noodles, allowing the preparation of hierarchical composite noodles.

Summary: Redox flow batteries (RFBs) show promise for grid-scale energy storage, but the performance of ion-conducting membranes used in RFBs needs improvement. This study developed high-performance RFB membranes using blends of carboxylate- and amidoxime-functionalized polymers, which exhibited both low ionic resistance and high selectivity towards redox-active species. The resulting microporous membranes demonstrated fast cation conduction and reduced crossover of redox-active molecules, leading to improved power ratings and reduced capacity fade in aqueous RFBs.

Summary: We have derived design principles for assembling rectangular tetramines into Zn8L6 pseudo-cubic coordination cages. The ligand panels' rectangular geometry and the handedness of each metal center at the corners of the pseudo-cube result in multiple possible cage diastereomers. However, our experiments showed that each tetra-aniline subcomponent assembled with zinc(II) and 2-formylpyridine into a single Zn8L6 pseudo-cube diastereomer. The preferred diastereomer depended on the subcomponent's aspect ratio and conformational flexibility.

Summary: Self-sorting in functionalized dipeptide systems can occur based on the chirality of a single amino acid, both in the micellar state at high pH and in the gel state at low pH. The resulting structures are influenced by the relative concentrations of the components, demonstrating the complexity of this approach. The gel network's structures are determined by the micellar structures at high pH. Using small-angle neutron scattering and cryo-transmission electron microscopy (cryo-TEM), we provide strong evidence for self-sorting in both the micellar and gel phases, showing complete self-sorting across a range of relative concentrations.

Summary: Gels formed from PBI can exhibit the photothermal effect, where the formation of PBI radical anions results in new absorption bands that can be used to induce heating of the gel through irradiation. We demonstrate the use of electrochemical methods and multicomponent systems to generate radical anions without UV light, and how this photothermal effect can be used to induce phase transitions in solutions above the gels.

Summary: Supramolecular assembly can be used to fabricate complex functional materials, but controlling hierarchical assembly across multiple length scales is difficult. This study investigates the correlation between a supramolecular gel network and a pre-gelling aggregate using a functional dipeptide 2NapFF. By varying the counterions, different micellar structures can be formed at high pH. Replacing the counterions with a divalent calcium salt results in a cross-linked gel network or an analog gel noodles.

Summary: Porous molecular materials are constructed from molecules that form cavities or interconnected pore networks. The assembly of these materials is challenging due to weak interactions between molecules and the potential for different crystal packing arrangements. By analyzing 1033 crystal structures, we determine the void spaces and potential guest diffusion networks in porous molecular materials. We find that while their packing arrangements resemble non-porous molecules, their pore distributions exhibit topological similarities to prominent porous materials such as metal-organic frameworks and covalent organic frameworks.

Summary: We investigated the effects of spatial constraints on hydrogels formed by dipeptide-based low molecular weight gelators. The gels were formed by either solvent switch or pH change methods in vessels of different sizes to produce gels of different thicknesses. Confocal microscopy and cavitation rheology were used to examine the microstructures and mechanical properties of the gels. Our results show that solvent-switch-triggered gels are sensitive to spatial constraints, while pH-triggered gels are not. These findings are important for applications requiring gels of different thicknesses.

Summary: Preparation of multicomponent systems allows for changing the properties of low molecular weight gelator-based systems. By varying the concentration ratio, we can tune the properties of the multicomponent systems before gelation, during gelation, and in the gel state. Changing the chirality of a single component also affects the properties of these systems. This work provides insights into tuning the properties of multicomponent systems composed of two gelators with the same basic structural design.
