| Popis: | The syntheses of two novel mechanically chiral rotaxanes containing urea and squaramide motifs (in yields of 33% and 22% respectively) are presented. 1H NMR spectroscopic titrations reveal shuttling of the macrocycle - detectable by modulation of the expression of mechanical chirality in the NMR spectrum - is possible through the addition of achiral chloride anions, a process which is reversed by the addition of sodium cations. |
