This work demonstrates an ew nonconventional ligand design, imidazole/pyridine-based nonsymmetrical ditopic ligands (1 and 1 S ), to construct ad ynamic open coordination cage from nonsymmetrical building blocks.Upon complex formation with Pd 2+ at a1 :4 molar ratio, 1 and 1 S initially form mononuclear PdL 4 complexes (Pd 2+ (1) 4 and Pd 2+ (1 S ) 4 )w ithout formation of ac age.T he PdL 4 complexes undergo astoichiometrically controlled structural transition to Pd 2 L 4 open cages ((Pd 2+ ) 2 (1) 4 and (Pd 2+ ) 2 (1 S ) 4 )c apable of anion binding,leading to turn-on anion binding. The structural transitions between the Pd 2 L 4 open cage and the PdL 4 complex are reversible.Thus,stoichiometric addition (2 equiv) of free 1 S to the (Pd 2+ ) 2 (1 S ) 4 open cage holding ag uest anion ((Pd 2+ ) 2 -(1 S ) 4 ·G À )e nables the structural transition to the Pd 2+ (1 S ) 4 complex, which does not have ac age and thus causes the release of the guest anion (Pd 2+ (1 S ) 4 + G À ).

Rückgrat‐verknüpfte Liganden erhöhen die Vielfalt in heteroleptischen Koordinationskäfigen

et al. 2020

View full text Add to dashboard Cite

Die Kombination von formkomplementären, bis‐monodentaten Liganden LA und LB mit PdII‐Kationen erlaubt das Selbstsortieren heteroleptischer Käfige der Formel cis‐[Pd2LA2LB2]. Wir berichten, wie solche Gebilde durch die Einführung kovalenter Brücken zwischen den Rückgraten zweier LA‐Einheiten diversifiziert werden können. Durch Lösungsmittel‐ und Gasteffekte wird gezeigt, dass die Flexibilität dieser Brücken die Zahl an Metallionen und Hohlräumen sowie die Topologie von vier Produkten bestimmt. Der Ligand LA1 mit flexiblem Linker reagiert in CH3CN mit seinem LB‐Pendant zu einem vierkernigen Dimer (D1). In DMSO wird ein dreikerniger Pseudotetraeder T1 gebildet. Das Produkt von starrem LA2 mit LB ähnelt D1, jedoch mit rotierter Ligandanordnung (D2). In Gegenwart eines Gastes wandelt sich D2 in Prisma P2 um. Wir zeigen, wie die Steuerung des Koordinationsmodus eines Liganden strukturelle Differenzierung auslösen und somit die Komplexität in der Metall‐vermittelten Selbstassemblierung erhöhen kann.

High‐Throughput Computational Evaluation of Low Symmetry Pd₂L₄Cages to Aid in System Design**

The use of unsymmetrical components in metallo-supramolecular chemistry allows for low-symmetry architectures with anisotropic cavities toward guest-binding with high specificity and affinity. Unsymmetrical ditopic ligands mixed with Pd(II) have the potential to self-assemble into reduced symmetry Pd 2 L 4 metallo-architectures. Mixtures of isomers can form, however, resulting in potentially undesirable heterogeneity within a system. Therefore it is paramount to be able to design components that preferentially
