Formation and Crystal Structure of Two-Component Host System Having Helical Chirality and Comprising 9,10-Dihydro-9,10-ethanoanthracene-11,12-diamine and 1,1′-Binaphthyl-2,2′-dicarboxylic Acid

A two-component supramolecular host system having multiple chiral points (central, axial, and helical), which can include an n-alkyl alcohol molecule, was successfully formed by combining (11R,12R)-9,10-dihydro-9,10-ethanoanthracene-11,12-diamine with central chirality and (S)-1,1′-binaphthyl-2,2′-dicarboxylic acid with axial chirality. The helical chirality of this host system was induced by the central and axial chiralities of the component molecules in solid state.
