An enantiopure ligand with four bidentate metal-binding sites and (S)-carbon stereocenters self-assembles octahedral ZnII or CoII to produce O-symmetric M8L6 coordination cages. The Λ- Δ-handedness of the metal centers forming corners these cages is determined by solvent environment: same (S)-ligand produces one diastereomer, (S)24-Λ8-M8L6, in acetonitrile but another opposite metal-center handedness, (S)24-Δ8-M8L6, nitromethane. Van 't Hoff analysis revealed Δ stereochemical configuration...
Here we demonstrate how the hydrogen-bonding ability of a BINOL-based dialdehyde subcomponent dictated stereochemical outcome its subsequent self-assembly into one diastereomeric helicate form when bearing free hydroxy groups, and another in case methylated congener. The presence methyl groups also altered self-sorting behavior mixed with another, short linear subcomponent, switching system from narcissistic to integrative self-sorting. In all cases, axial chirality BINOL building block...
We report the construction of three structurally distinct self-assembled architectures: FeII12L12 pseudoicosahedron 1, FeII2L3 helicate 2, and FeII4L4 tetrahedron 3, formed from a single triazatriangulenium subcomponent A under different reaction conditions. Pseudoicosahedral capsule 1 is largest through self-assembly to date, with an outer-sphere diameter 5.4 nm cavity volume 15 nm3. The outcome depended upon concentration, where formation was favored at higher concentrations, while 2...
Paper-based assays such as lateral flow are good candidates for portable diagnostics owing to their user-friendly format and low cost.
Abstract Biomolecular systems show how host–guest binding can induce changes in molecular behavior, which turn impact the functions of system. Here we report an artificial system where dynamic adaptation during guest alters both host conformation and dynamics. The self-assembled cage employed here possesses concave walls a chirotopic cavity. Complementarity between curved surfaces fullerenes inner surface cavity leads to reconfigure stereochemically order bind these guests optimally....
Abstract Organic semiconductors are promising for efficient, printable optoelectronics. However, strong excited‐state quenching due to uncontrolled aggregation limits their use in devices. We report on the self‐assembly of a supramolecular pseudo‐cube formed from six perylene diimides (PDIs). The rigid, shape‐persistent cage sets distance and orientation PDIs suppresses intramolecular rotations vibrations, leading non‐aggregated, monomer‐like properties solution solid state, contrast fast...

Metal-organic cages have served as masks to effect the regioselective functionalization of C60. The enantioselective C60 remains challenging, however, requiring complex chiral tethers or challenging chromatography. We report a means defining up six stereocentres on C60, achieving both and fullerene functionalisation. This method involves stereochemical information transfer from formylpyridine, through framework an enantiopure cage incorporating it, series regio- stereochemically defined...
A supramolecular chromophore cube based on perylene diimides (PDIs) is reported by Sascha Feldmann and co-workers in their Research Article (e202216729). The rigid shape-persistent cage preserves the electronic purity of its PDI constituents enables observation delayed fluorescence because bright excited multimer state, acting as an excitation reservoir. Self-assembly can thus serve a powerful tool for controlling properties molecular electronics devices. Batteries Bioinorganic Chemistry...

Small molecule organic semiconductors hold great promise for efficient, printable, and flexible optoelectronic applications like solar cells displays. However, strong excited-state quenching due to uncontrolled aggregation currently limits their performance employability in devices. Here, we report on the self-assembly of a supramolecular pseudo-cube formed from six modified tetradentate perylene diimides (PDIs). The rigid, shape-persistent cage sets distance orientation PDI chromophores...
