Helical Arrangement of Interstrand Stacked Pyrenes in a DNA Framework

Getting it together: Helical self‐organization between oligopyrene strands with 14 consecutive achiral pyrene building blocks embedded in a DNA strand leads to an artificial double helix (see example, oligopyrene regions are shown in dark colors and the flanking DNA regions in light colors). Helicity within the interstrand‐stacked oligopyrenes is evident from the observation of exciton‐coupled CD signals originating from the pyrene moieties.
