AI Article Synopsis
- The study explores the construction of complex supramolecular structures using specific coordination compounds, including a unique non-intertwined ring-in-ring assembly and an unusual trefoil knot.
- These structures were formed using a chosen building block and a specially designed ligand that drives self-assembly.
- Remarkably, the research demonstrates that these shapes can reversibly transform into each other through the joint influence of silver ion coordination and changes in the solvent, supported by advanced X-ray crystallography and NMR findings.
Article Abstract
The synthesis of complicated supramolecular architectures and the study of their reversible structural transformations remains a fascinating challenge in the field of supramolecular chemistry. Herein, two types of novel coordination compounds, a non-intertwined ring-in-ring assembly and an abnormal trefoil knot were constructed from a strategically selected Cp*Rh building block and a semi-rigid ,'-bis(4-pyridylmethyl)diphthalic diimide ligand coordination-driven self-assembly. Remarkably, the reversible transformation between the abnormal trefoil knot and the ring-in-ring assembly or the corresponding tetranuclear macrocycle could be achieved by the synergistic effects of Ag ion coordination and alteration of the solvent. Single-crystal X-ray crystallographic data and NMR spectroscopic experiments support the structural assignments.
