AI Article Synopsis
- - Two new compounds, a molecular trefoil knot and a Solomon link, were created using multiple interactions known as π-π stacking.
- - The trefoil knot can reversibly transform into a macrocycle depending on the solvent and guest, while the Solomon link remains stable under varying conditions.
- - Techniques like X-ray crystallography, NMR spectroscopy, and ESI-MS were used to confirm their structure and synthesis, paving the way for innovative smart materials and biomaterial designs.
Article Abstract
Two novel compounds, a molecular trefoil knot and a Solomon link, were constructed successfully through the cooperation of multiple π-π stacking interactions. A reversible transformation between the trefoil knot and the corresponding [2 + 2] macrocycle could be achieved by solvent- and guest-induced effects. However, the Solomon link maintains its stability in different concentrations, solvents and guest molecules. Single-crystal X-ray crystallographic data, NMR spectroscopic experiments and ESI-MS support the synthesis and structural assignments. These synthesis methods open the door to the further development of smart materials, which will push the advancement of rational design of biomaterials.
