Summary: This study presents novel piezoelectric force and touch sensors based on self-assembled monolayers of oligopeptides, which show large piezoelectric voltage response and are easily manufactured. Despite modest piezoelectric charge constants, the devices exhibit immense piezoelectric voltage constants. Additionally, a flexible device prototype with high open-circuit voltages is demonstrated, with potential for further improvements in voltage response through peptide selection and device construction.

Summary: Carbohydrates are considered as an ideal candidate for chirality study due to their unique chemical structures, abundance, and sustainability. Efforts have been made to design and synthesize diverse carbohydrate derivatives and self-assemble them into various supermolecular morphologies. However, there is still insufficient understanding of how carbohydrate structures and self-assembly approaches affect the final morphologies and properties for future demands.

Summary: Materials that can undergo reversible changes typically require top-down processing for microstructure programming, making it difficult to program microscale 3D shape-morphing materials that deform in non-uniaxial ways. However, a new bottom-up approach is described here, using liquid crystal monomers with controlled chirality to create bending microactuators. By adjusting the concentration of chiral dopants, the bending behavior of these microactuators can be controlled. The asymmetric molecular alignment within the 3D structure confirms the effectiveness of this fabrication method.

Summary: Chirality is important in natural and life sciences, and chiral materials are widely used for electrochemical chiral recognition. Carbon quantum dots have shown potential as a novel carbon nanomaterial due to their unique properties. Self-assembly of achiral porphyrins induced by chiral carbon quantum dots was demonstrated, and the resulting structure showed good electrochemical chiral recognition properties. This research provides a new approach for synthesizing chiral composites and expanding the applications of electrochemical chiral recognition.

Summary: It is shown that aqueous dispersions of negatively charged inorganic nanoparticles can induce the chiral assembly of organic radical cations at the liquid-liquid interface, resulting in stable droplets covered by inorganic/organic chiral nanocomposites. Transfer of chirality from chiral organic monomers to the nanoparticle assemblies is observed. Surprisingly, opposite handedness between molecular assemblies and nanoparticle assemblies is determined. Moreover, the functionalities of these chiral droplets can be further engineered through mixing or merging, enabling the production of fluorescent emissive-tunable, magnetic, as well as magnetofluorescent dual-functional droplets.

Summary: Chiroptical nanomaterials, such as CdSe/CdS chiral films, have been assembled using the Langmuir-Schaeffer technique to achieve high CPL signals. The symmetrical chiral films with ten layers and a 45-degree inter-angle exhibited the highest CD activity and strong CPL signals. The birefringence and dichroism of the well-aligned CdSe/CdS nanorod layers contributed to the remarkable optical activity.

Summary: In this study, a postmodification protocol was developed to attach a chiral cholesteryl pendant to metal-organic polyhedra (MOPs) through covalent conjugation, enabling the self-assembly of chiral superlattices. The postmodification process preserved the coordination cores and allowed for reaction-induced self-assembly in loosely packed nanosized columns. Solvent-processed bottom-up self-assembly in aqueous media resulted in twisted superlattices with a 5 nm lattice parameter. The intercholesteryl forces were found to play a crucial role in the rotation of nanosized MOPs and the transfer of chirality to the supramolecular scale. This work presents a novel approach to the rational design of chiroptical materials based on MOPs for potential applications in enantioselective adsorption, catalysis, and separation.

Summary: A simple solution-based self-assembly method is reported to construct chiral superstructures from copper-penicillamine nanosheets. These chiral copper superstructures feature flower-like morphology and exhibit significantly stronger circularly polarized light emission than their unassembled counterparts. Furthermore, the chirality and the morphology complexity of the superstructures can be independently manipulated by the chirality of penicillamine enantiomers and self-assembly process, respectively.

Summary: The self-assembly of chiral metal nanoclusters into ordered microstructures with enhanced phosphorescence and optical activities was achieved by manipulating Au nanoclusters modified by L-/D-cysteine. The compact aggregation structures were essential for emission enhancement and chirality amplification, with the microflowers exhibiting pH-responsiveness. Additionally, the pH-responsive photoluminescence ON/OFF switch of the microflowers could be utilized for reliable information encryption and decryption.

Summary: A novel chiral nematic phase Np* with a polar helical order has been realized, which is characterized by a continuously twisted polarization and ultrafast electro-optic switching performance. The properties of Np* differ from conventional cholesteric phases and have been confirmed through transmission spectroscopy and measurements. This unique Np*LC structure suggests new potential applications for electrically interchangeable photonic bandgaps.

Summary: Hydrogen-bonded polymers are highly dynamic supramolecular aggregates that can self-assemble through external or internal stimuli. This study finds that chiral biphenyldiimides derived from amino acids can self-assemble into open-chain 1D supramolecular polymers, and the amino acid side chains play an important role in stabilizing or destabilizing the assemblies. Significant differences in the polymerization process are observed between dynamic liquid and static solid. This work demonstrates the potential of diimide-based organic dyes in the formation of chiral supramolecular assemblies with tunable properties.

Summary: Electronic circular dichroism (ECD) is a valuable tool for monitoring the self-assembly of chiral peptide-based capsules, allowing separation of non-specific processes and restriction of intramolecular motion caused by discrete self-assembly. Experimental and theoretical ECD spectra analysis reveal the differences between assembled and non-assembled species originate from induction of inherently chiral conformation and restriction of conformational freedom leading to amplification of ECD signals during self-assembly of discrete species.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
