| Abstract: | A procedure for studying “dynamic structural behavior” of large chiral macrocycles is presented. Ion mobility MS, diffusion‐ordered NMR spectroscopy (DOSY NMR), and optical rotation (OR) measurements, supported by calculations, are used together as effective complementary methods to study dynamic formation of noncovalent aggregates. It is shown that the monomer–dimer equilibrium is driven by π–π or CH–π interactions and controlled largely by the substitution pattern of the calixsalen skeleton. |
