Organisation of long aliphatic monocarboxylic acids in β-cyclodextrin channels: crystal structures of the inclusion complexes of tridecanoic acid and (Z)-tetradec-7-enoic acid in β-cyclodextrin

In the crystalline state, infinite channels of β-cyclodextrin dimers host infinite arrays of self associated linear aliphatic monocarboxylic acids, thus enclosing the hydrophilic carboxy ends inside the hydrophobic channels.
