Summary: π-Conjugated polymers have unique properties that depend on their ordering, with programming techniques such as covalent and solution programming playing a key role in controlling their assembly. Progress in programming at different stages of material development highlights order-dependent features and unique assembly techniques for pi-conjugated polymers.

Summary: This study introduces a hybrid DNA origami-based approach for dynamic templating of supramolecular architectures, allowing for selective recruitment of supramolecular polymers to the platform with dynamic tuning of composition. This platform aids in real-time study of supramolecular structures in their native environment and promotes new strategies for controlled multicomponent self-assembly.

Summary: Photosensitive azobenzene conjugated phenylalanines were used as building blocks to construct superhelical nanostructures with controllable handedness and switchable morphology. These hierarchical superhelices highly depended on the solvent ratio and the concentration of the phenylalanine derivatives. Additionally, the chiral superstructures could be reversibly switched into achiral nanorods upon UV or visible light irradiation.

Summary: The study introduces a unique evaporation-induced self-assembly (EISA) strategy for four different silica nanoparticle systems obtained through peptide functionalization of the particle surface. The research shows that this EISA-based approach provides new possibilities for the design of future advanced drug delivery systems, engineered hierarchical sorbents, and nanocatalyst assemblies.

Summary: This study presents an interesting self-assembly phenomenon of peapod-like micrometer tubes from a planet-satellite-type supramolecular megamer. The peapod-like structure is formed through sequential vesicle entosis, linear association, and fusion processes. Dissipative particle dynamics (DPD) simulations support the possibility of the structural formation and its mechanism. UV light irradiation can disassemble the peapod-like structure. This study expands the family of supramolecular polymers and provides a new avenue for developing bioinspired complex hierarchical nanoarchitectures at the microscopic level.

Summary: Enzymes are widely used in various fields for their remarkable catalytic properties, which are mainly due to the spatial arrangement of the essential functional groups in their active structures. Building enzyme-like active sites in artificial catalysts, which aim to rival native enzymes in catalytic efficacy, is a challenge. De novo designed peptides have been used as building blocks to self-assemble into enzyme-mimicking catalysts by configuring their side chain groups to form catalytically active pockets. This review discusses the progress, structure-activity relationships, and future directions of peptides-based supramolecular catalysts with aldolase-, hydrolase-, and oxidase-like activities.

Summary: This study reports the diverse morphological and conformational versatility of a biologically active peptide (PEP-1), which can form up to six distinct nanostructures and up to four different secondary structures through subtle modulation in pH, concentration, and temperature. PEP-1 also shows high biocompatibility, low hemolytic activity, and marked antibacterial activity, making it a promising candidate for multiple bio-applications.

Summary: The research found that vibrational strong coupling can significantly change the molecular supermolecular morphology of self-assembly, affect self-assembly dynamics, and depend on solvent vibration. These findings provide a new tool for controlling supramolecular assemblies, with broad implications for molecular and material science.

Summary: Controlled self-assembly is of great interest in biological and nanotechnological applications. We have demonstrated a light-triggered platform that allows precise control of self-assembly from nanoparticles into nanofibers in living cells. The process is biocompatible, fast, and can be applied for regulating molecular assembly in living cells.

Summary: This study reports four novel p-conjugated macrocycles based on electron acceptor units naphthalimide (NMI) with aryl or alkyl substitutions. The self-assembly behaviors of these macrocycles were greatly affected by the different substitutions. Alkyl substituted macrocycles showed aggregation in solution, while aryl substituted macrocycles did not. Furthermore, all the macrocycles exhibited supramolecular encapsulation with C-70, with larger macrocycles showing stronger binding affinity than smaller macrocycles.

Summary: Supramolecular polymers, constructed through self-assembly of noncovalent interactions like host-guest interaction, have both the advantages of traditional polymers and unique characteristics. Crown ethers, as a widely used host molecule, can be easily modified and derivatized, making them ideal candidates for the fabrication of interesting supramolecular polymers.

Summary: Molecules with C-3 symmetry and conjugated diacetylene cores can self-assemble into well-defined supramolecular fibers with enhanced chirality in both organic and aqueous solutions. The integration of symmetry and conjugation provides aggregation tendency through pi-pi stacking, resulting in supramolecular chirality predominantly influenced by steric hindrance from dipeptide pendants.

Summary: This study investigates the self-assembly of R5 peptides and reveals that they form large aggregates with a mass-fractal structure composed of small spherical aggregates. Additionally, it is discovered that phosphate ions not only drive the growth of the R5 scaffold but also promote the polycondensation of silicic acid through electrostatic interactions during the biosilification process.
