Summary: Inspired by the signal transduction function of organophosphates, bioactive organophosphates were used as chiral nodes to control the stereoselective assembly of hydrogen-bonded anionic cages. Antibiotics such as phosphonomycin and clindamycin phosphate, antiviral drug tenofovir, and natural product AMP were assembled with an achiral bis-monourea ligand to form quadruple or triple helicates with stereoselectivity. The stereoselectivity could be enhanced by lowering temperature or using stronger-binding cations as templates. Enantioselectivity was achieved when binding chiral quaternary ammonium cations with the chiral anionic cages as hosts.

Summary: This study presents a novel metal/anion-coordination co-driven strategy for the synthesis of nanoscale supramolecular metallocycles with unique topology and desired chirality. The enantiomeric Janus-type metallocyclic strips are formed through the synergistic coordination of sulfate anions and Co-II ions to a bifunctional chiral ligand. The chirality is derived from two types of helical chiralities, namely triply twisted Mo''bius ring and circular helicate, which represent a new phenomenon in metal-organic complex systems.

Summary: This study reports the first example of polyhedral oligosilsesquioxane (POSS) derivatives that can self-assemble into well-defined chiral nanoassemblies. These chiral nanoassemblies exhibit active chiroptical responses and can bind guest molecules through charge-transfer interactions, offering a new design protocol for functional chiral materials.

Summary: The introduction of multiple kinetic aggregation states (Aggs) into the self-assembly pathway can increase the complexity and flexibility of the self-assemblies. This was achieved by using a series of chiral and achiral d(10) Au-I bis(N-heterocyclic carbene, NHC) complexes, where the achiral complex could undergo self-assembly with multiple kinetic Aggs. The chiral Au-I self-assemblies exhibited nonlinear optical response of second harmonic generation (SHG) and could function as optical waveguides with strong emission polarization, while these properties were absent in the achiral analogue.

Summary: Chemists have constructed sophisticated artificial nanostructured systems through self-assembly, including scissor-shaped photochromic dyads that hierarchically self-assemble into discrete nanostructures with photoresponsive properties. These nanostructures, such as azobenzene dyads, can be dissociated and reorganized through the photoisomerization of azobenzene units, enabling controllable and adjustable structures.

Summary: Metal nanoclusters have attracted attention as a new type of fluorescent material due to their good biocompatibilities and outstanding optical properties. This study investigates the self-assembly of atomic precise silver nanoclusters through supramolecular interactions, and demonstrates their ability to form highly luminescent hydrogels with chiral properties. The resulting nanocluster-based hydrogel shows selectivity and sensitivity in detecting small biological molecules, making it a promising candidate material in the fields of sensors and biological sciences.

Summary: This study shows that transient and high-energy self-assembly intermediates in coordination self-assembly reactions can be obtained through ball-milling approaches. These intermediates, which are difficult to access in solution-based reactions, are successfully trapped in the solid state. The structures of these intermediates are determined using various characterization techniques. The results highlight the opportunity of using mechanochemistry to study coordination self-assembly reactions in a different chemical space compared to conventional solution-based approaches.

Summary: This study presents the chiral induction and memory effect in an anion-coordination-driven tetrahedral cage. The induced chirality can be retained for a certain period even after replacing the chiral guests with achiral ones. The retention time of induced chirality can be controlled by using different achiral guests.

Summary: This study introduces a strategy to incorporate four members of the classic coal-tar dye family into [Pd2L4] self-assemblies, investigating their performance in different ligands and color ranges, showing potential applications in chiroptical recognition, photo-redox catalysis, and optical materials. The results demonstrate different behaviors of the self-assemblies based on this new ligand class, such as chiral induction, binding modes distinction, and rearrangement to new structures.
