Figure 5. NMR spectroscopic analysis and assignment of (OMe-cube)3.

Figure 5

a Full 1H NMR (700 MHz, 375 K, Toluene-d8) spectrum of (OMe-cube)3. Partial 1H NMR (700 MHz, 375 K, Toluene-d8) showing twelve different types of b imine peaks and c methyl peaks of (OMe-cube)3. Cartoons of the d [(OMe-cube)@(OMe-cube)]@(OMe-cube), e (OMe-cube)@(OMe-cube)@(OMe-cube), f syn-distal and g syn-proximal trimeric catenanes highlighting the 12, 12, 36 and 72 different magnetically equivalent imine protons in different colour codes respectively.
