Abstract The design and assembly of interlocked supramolecular cages is a highly important research topic, mainly due to their exquisite topological configuration excellent performance in variety application fields. Herein, we introduce the preparation two new carbazole-based ligand precursors, L1 L2, which were rationally designed form three molecular-tweezer like compounds, cages, tetranuclear macrocycle hexanuclear cage via combination with four different half-sandwich rhodium based building blocks, E1-E4. structure these compounds was determined by single crystal X-ray diffraction analysis, NMR spectroscopy ESI-TOF-MS analysis. Owing stacking interactions between carbazole groups appropriate size obtained. Furthermore, photothermal conversion isolated studied detail. 5, 6, 7, exhibiting broad-band absorptions from UV-Vis NIR region remarkable conversion, used prepare membranes 5', 6', 7', study steam generation promoted solar energy.

Metal–organic cages (MOCs) are discrete supramolecular entities consisting of metal nodes and organic connectors or linkers; MOCs noted for their high porosity processability. Chemically, they can be post-synthetically modified (PSM) new functional groups introduced, presenting attractive qualities, it is expected that properties will differ from those the original compound. This why highly regarded in fields biology chemistry. The present review deals with current PSM strategies used MOCs, including covalent, coordination, noncovalent methods structural benefits. main emphasis this to show what extent under circumstances a MOC designed obtain tailored geometric architecture. Although sometimes unclear when examining systems, particularizing design systematic approaches development characterization families provides insights into structure–function relationships, which guide future developments.

The self-assembly of metallo-supramolecules has attracted considerable attention in recent decades. These discrete architectures are primarily driven by coordination interactions, typically involving M-N/O (Werner-type) or M-C (organometallic) bonding. However, the use M-π interactions for constructing these multinuclear complexes remains largely unexplored. In this work, we report trinuclear and tetranuclear copper(I) a combination interactions. Cu(I)-NHC were synthesized from nido-carborane-supported N-heterocyclic carbene (NHC) precursors Cu(I) ions. solution, dynamic equilibrium between species was observed, as confirmed variable-temperature NMR spectrum. Van't Hoff analysis revealed that is endothermic (ΔHeq = 53.6 kJ mol-1) entropically (ΔSeq 158 J mol-1 K-1). solid-state structures both forms elucidated through single-crystal XRD analysis. Density functional theory calculations showed Cu-CNHC bonds relatively weak (∼100 mol-1, approximately one-third strength typical bonds). This attributed to strong Coulombic attraction positively charged negatively nido-carborane ligands (M-π interactions), which significantly reduces bond neutral NHC moieties (M-C bonding).

Realizing topological transformation through supramolecular fusion is particularly challenging, as the self-assembly of disparate components often results in orthogonal assembly building blocks into distinct structures rather than formation a heteroleptic architecture. This study introduces transformation, transitioning from figure-eight knot (4

Supported by chiral stationary phase high-performance liquid chromatography HPLC (CSP-HPLC), examples of mechanically interlocked organic molecules, including knots, rotaxanes, and catenanes, have been reported. However, the exploration stereoselective construction cationic complexes, particularly those induced point chirality, has notably limited due to constraints posed type chromatographic columns separation efficiency. To address this, we developed a strategy for generating coconformational helical topologically [2]catenanes through induction chirality. In this study, adjusting symmetry ligand, easily realized efficient high-yield crystalline [2]catenanes. Moreover, within enantiomerically pure environment molecular self-assembly driven L -alanine -valine residues in bidentate ligands, exist exclusively as single enantiomer, thus eliminating need laborious CSP-HPLC from racemic mixtures. The generation opposite enantiomer can be employing unsymmetrical ligands containing corresponding D residues, confirmed single-crystal X-ray diffraction, elemental analysis, electrospray-ionization time-of-flight mass spectrometry, solution-state NMR spectroscopy, circular dichroism spectroscopy.
