Chiral self-sorting during the formation of cage-like molecules continues to fascinate and advance our understanding of the phenomenon in general. Herein, we report the chiral self-sorting in the Pd L -type metal-organic cages. When a racemic mixture of axially chiral bis-pyridyl ligands undergo coordination-driven self-assembly with Pd(II) ions to form Pd L -type cages, the system has the option of chiral self-sorting to afford any of at least 70 pairs of (one homochiral and 69 heterochiral) enantiomers and 5 meso isomers or a statistical mixture of everything. However, the system resulted in diastereoselective self-assembly through a high-fidelity chiral social self-sorting to form a racemic mixture of D symmetric heterochiral [Pd (L ) ] /[Pd (L ) ] cages.

Article Synopsis
  • Researchers have created decanuclear chiral gold(I) sulfido clusters (S-Au and R-Au) using specialized SDP ligands.
  • Mixing these chiral clusters in a 1:1 ratio yields an achiral heterodimer icosanuclear meso-cluster (meso-Au), which exhibits intense near-infrared luminescence with a peak at around 750 nm.
  • The study highlights the significant increase in photoluminescence quantum yield for meso-Au (25%) compared to the chiral clusters (8%), and shows that the clustering process is influenced by solvent polarity and diphosphine ligand configuration, aiding the understanding of self-sorting in chiral assemblies.

Several BINOL-derived C2-symmetric aldehydes were synthesized to investigate chiral self-sorting phenomena during macrocycle formation in the presence of aliphatic and aromatic bisamines. While self-sorting was unsuccessful with aliphatic amines, aromatic amine dictated complete homochiral self-sorting, confirmed by H NMR analysis and molecular modelling. Additionally, the impact of macrocyclization on the chiroptical properties of these macrocycles was examined.

Solvent-Directed Social Chiral Self-Sorting in PdL Coordination Cages.

A family of Pd cages prepared from ligands based on an axially chiral diamino-[1,1'-biazulene] motif (serving as a unique azulene-based surrogate of the ubiquitous BINOL moiety) is reported. We show that preparing a cage starting from the racemate of a shorter bis-monodentate ligand derivative, equipped with pyridine donor groups, leads to integrative ("social") chiral self-sorting, exclusively yielding the product, but only in a selection of solvents. This phenomenon is driven by individual solvent molecules acting as hydrogen bonding tethers between the amino groups of neighboring ligands, thereby locking the final coordination cage in a single isomeric form.

Article Synopsis
  • The study focuses on how chiral imidazoline-based C-symmetric ligands interact with zinc (II) and copper (II) ions using two types of bisimidazoline ligands.
  • One ligand has a free amine group while the other has the amine protected, allowing for different complex formations.
  • The research demonstrates that by choosing specific ligand types (either enantiopure or racemate), it’s possible to control the creation of complex structures through chiral design.

Stereospecific supramolecular polymerization of nanoclusters into ultra-long helical chains and enantiomer separation.

During the construction of supramolecular polymers of smaller nanoparticles/nanoclusters bearing hierarchy and homochirality, the mechanism understanding via intuitive visualization and precise cross-scale chirality modulation is still challenging. For this goal, a cooperative self-assembly strategy is here proposed by using ionic complexes with uniform chemical composition comprising polyanionic nanocluster cores and surrounded chiral cationic organic components as monomers for supramolecular polymerization. The single helical polymer chains bearing a core-shell structure at utmost length over 20 μm are demonstrated showing comparable flexibility resembling covalent polymers.
