Abstract Experimental evidence is provided that tentatively shows a relationship between inclusion and sorption properties within a series of halogenated homochiral calixsalens. Calixsalens with Cl and Br substituents at the C5 position on the aromatic rings display remarkable sorption properties for all of the investigated gases, as well as the ability to form inclusion compounds with chemically different
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 dynamicformation of noncovalentaggregates. It is shown that the monomer–dimer equilibrium is driven by π–π or
