Guest mols. confined inside hollow mol. assemblies and thus protected from their environment can show unexpected structural behavior or special reactivity compared to their behavior in a bulk, unprotected environment. A special case is the coiling behavior of variable-length alkane chains in rigid hydrogen-bonded mol. cages. It has been found before that coiling may occur in such circumstances, but no exptl. evidence concerning the exact conformation of the chains has yet been presented. Self-assembly of a mol. cage in water and the crystalline state from three distinct components in which linear 1,ω-diammonium-alkanes chains are confined with different degrees of compression are reported. The exact coiling behavior is determined from at. resolution X-ray diffraction showing crenel-like conformations in the compressed state. Chem. selection can be obtained from mixtures of alkane chains via the encapsulation of kinetically stable conformations observed during the encapsulation of pure components. Moreover, it was found that uncompressed and compressed chains can be competitively trapped inside the capsule. These findings may provide insight in areas to a better understanding of biol. processes, such as the fatty acid metabolism
