摘要：

Do the twist: A helicenebisquinone (see formula), both enantiopure and racemic, forms hexagonal columnar phases in which the internal structures of the columns are 132 hollow helices comprising six-molecule repeat units (see axial and side views). The enantiopure compound forms a true hexagonal structure; the racemate segregates enantiomers into right and left helical columns that are interlocked and longitudinally displaced for optimal packing. © 2009 Wiley-VCH Verlag GmbH & Co.
