AI Article Synopsis
- Self-assembly of metallo-interlocked architectures is appealing, but they can be diluted due to the presence of smaller species in equilibrium.
- The study introduces a junctioned system that consistently forms a trefoil-entangled tetrahedron, regardless of the concentrations used.
- Heating the sample allows for a reversible shift from the entangled structure to a non-interlocked dual metallo-cycle, indicating that thermal changes can be used to switch structures even without concentrating the components.
Article Abstract
Self-assembly makes metallo-interlocked architectures attractive targets, but being in equilibrium with smaller species means that they can suffer from dilution effects. We show that a junctioned system gives rise to a [Pd (L) ] trefoil entangled tetrahedron irrespective of concentration. Heating the sample reversibly shifts the equilibrium from the knot to an isomeric non-interlocked dual metallo-cycle, demonstrating that thermodynamic equilibria can still be exploited for switching even in the absence of concentration effects.
