Summary: We report a terpyridine-based metallo-cage that can undergo controlled hierarchical self-assembly of superstructures in response to different halide ions. By adding Cl-/Br- or I-, drastically different hierarchical superstructures with highly-tight hexagonal packing or graphite-like packing arrangements, respectively, have been achieved. These unusual halide-ion-triggered hierarchical structural changes provide new insights into the mechanism of supramolecular aggregation and crystal growth.

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: The study found that tree-shaped fractal patterns could be self-assembled from Fmoc-Glu and ZnTPyP, composed of nanorod aggregate arranged in a spiral fractal way. The formation and growth of initial nucleon led to the fractal patterns, and the spiral packing and their branches were closely related to the absolute configuration of Fmoc-Glu.

Summary: By introducing molecular chirality based on amino acid derivatives (TDAP), the morphological transformation from microspheres to helical supramolecular nanofibers with controllable handedness is achieved. The chirality of the supramolecular architectures is nullified through the coassembly of the equivalent TDAP enantiomers. The molecular detection of achiral melamine based on the R-TDAP-COOH supramolecular system is achieved through the appearance of helicity and inversion.

Summary: In this study, a strategy for the conformational control of metallo-supramolecular cages via the enhancement of ligand dissymmetry was proposed. Four dissymmetrical ditopic ligands were designed and synthesized, allowing for precise control of assembly conformations to form discrete cis-PdnL2n molecular cages by increasing the dissymmetry of length or angle.

Summary: This study focuses on the construction of tunable fluorescent supramolecular assemblies using 2,2 ':6 ',2''-terpyridine and metal Zn(II). Two luminous 3D supramolecular prisms were prepared and the effect of hydrophobic alkyl chains on tunable fluorescence emission was investigated. The results show that hydrophobic properties enable the supramolecular prisms to exhibit tunable visible-light emission and form helical nanofibers.

Summary: Nature offers a variety of transient interactions, which have inspired the introduction of different supramolecular assemblies in synthetic materials to achieve biomimetic functions. Metal-ligand coordination, as one of the most commonly used transient bonds, plays a crucial role in the design of robust and stimuli-responsive metallo-supramolecular polymer networks (MSPNs). However, the coordination geometry of the metal complex is often overlooked, despite significant advancements in controlling the spatial configuration of supramolecular coordination complexes (SCCs). This article classifies existing reports on the coordination geometry of MSPNs and reviews relevant self-sorting mechanisms of SCCs, highlighting the potential of coordination geometry as a new design parameter in polymeric systems.

Summary: This study investigates the effect of solvent on chirality transfer and energy transmission in supramolecular polymer system and identifies the hierarchical assembly behavior regulated by the solvent effect. A designed AIE-core building block shows morphologic transformations with chirality amplification for both CD and CPL measurements. Time-dependent CD test demonstrates the hierarchical assembly of aggregates. The results contribute to the development of supramolecular materials with enhanced CPL performance and dynamic chirality.

Summary: In this study, a new building block for 2D supramolecular assembly called thiophene (TDAV), which is derived from amino acids, is designed. Various square and rectangular microsheets with precisely regulated aspect ratios are achieved by controlling the polarity of cosolvent or water content. Additionally, the introduction of chirality leads to the formation of a novel microsaw. This research provides a new approach to prepare various kinds of unique supramolecular 2D materials with controllable shapes and sizes for future biological applications.

Summary: This study demonstrates the deliberate control of hierarchical assembly of protein-DNA materials by exploiting the chemical anisotropy of proteins and the programmability of DNA ligands. The introduction of orthogonal DNA interactions with disparate strengths onto specific geometric regions of a model protein leads to directional assembly and increased multi valency through DNA sequence design. The judicious DNA design not only directs assembly along a specific pathway but also influences distinct structural outcomes from a single pathway.

Summary: Regioselective di-functionalization of a cyclodextrin enables controlled orientation of hydrophobic domains, leading to a unique hierarchical assembly in the solid state. This assembly involves synergistic host-guest inclusions, directed hydrophobic effect, and hydrogen bonding, which together create a porous organic architecture.

Summary: Weakly coordinating anions (WCAs) have garnered significant attention for their ability to stabilize highly reactive cations. However, there is still a lack of profound understanding regarding the definition of WCAs and limited systematic studies on counterion effects. This study investigates the formation of a supramolecular pseudorotaxane, exploring various anions with different coordination strengths, to enhance our understanding of anion coordination properties and mechanical bond nature. Advanced DFT-based methods, along with isothermal calorimetry and H-1 NMR experiments, are employed to calculate anion-dependent Gibbs free association energies ?G(a) and evaluate intermolecular interactions. Correlations between ?G(a) and anions' solvation energies are discovered, which are utilized to calculate physico-chemical reaction parameters related to coordinating anions. Additionally, the study reveals that the binding situation within (pseudo)rotaxanes can be largely explained by electrostatic considerations, although quantum-chemical effects become increasingly relevant with the use of WCAs.
