WebSep 15, 2024 · 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. WebJan 9, 2024 · The science and mathematics of knots, however, is a relatively recent development. In the 19 th century Lord Kelvin proposed an atomic theory in which the elements could be described as knots in the luminiferous ether. For example, sodium, with its two spectral lines, could be considered as two interlocked rings—a Hopf link (Figure …
