The endeavor to enhance utility of organic molecular cages involves the evolution of them into higher-level chiral superstructures with self-similar, presenting a meaningful yet challenging. In this work, 2D tri-bladed propeller-shaped triphenylbenzene serves as building blocks to synthesize a racemic ...
When a similar reaction is performed in an organic media (Me2SO or MeCN) instead of water, the resulting product changes to a topologically trivial macrocycle assembled from two equivalents of the tetraformyl precursor and four equivalents of the chiral bisamine. This result indicates unambiguously ...
General design principles for self-assembly of discrete, large metal-organic cages composed of numerous components are challenging to develop. Here, the authors use remote geometric communications between components to realize several types of metal–organic assemblies based on dihedral angle control in ...
Coordination chemistry is a powerful method to synthesize supramolecular cages with distinct features that suit specific applications. This work demonstrates the synthesis of discrete, homochiral FeII 2L3 cages via chirality-driven self-assembly. Specifically, the installation of chirality – at both the...
cages formed upon self-assembly. As the reaction medium influences the binding of the reactants and products in subtle but important ways, control over host solubility through host framework charge and substituent effects provides further means to control guest binding strengths, selectivity, and ...
But these cages usually lack stability, diversity of function groups, which limit the application of these cage molecules in supramolecular self-assemblies. The chemical stable organic cages, especially the heteracalixaromatic cages, usually were synthesized via multistep fragment coupling strategies, ...
A new metal–organic framework (MOF) based on metal clusters as secondary building units (SBU), has been synthesized and structurally characterized. The reported MOF presents an interesting 8-connected self-penetrating coordination network based on dinuclear cadmium cluster with a 424·5·63 topology...

to self-organize into uniform quaternary and double helical structures with a controlled handedness, respectively, through noncovalent interactions even within complex mixtures of subunits or molecular strands with a similar shape, size and sequence, thereby providing sophisticated functions that are essentia...
controlling the topology and coordination geometry. Similar to linear helicates, tetrahedral cages are intrinsically chiral with either a Δ or Λ configuration at each of the four vertices. However, due to the different constraints in metal coordination geometry, tetrahedral cages may result in ...
