- Abstract: Helical carbazole‐based BODIPY analogues were readily synthesized via aza[7]helicenes. The structures of azahelicene‐incorporated BF2 dyes were elucidated by x‐ray diffraction analysis. DFT calculations revealed that the π‐conjugated system expanded from the helicene moiety to the BODIPY framework. The azahelicene‐fused boron complexes showed the Cotton effects and the circularly polarized luminescence (CPL) in the visible region. Furthermore, an axially chiral binaphthyl group was attached to the helically chiral dyes, which enhanced the chiroptical properties. Abstract : Eine polarisierende Wendung : Helikale Borkomplexe auf Carbazol‐Basis wurden leicht über Aza[7]helicene synthetisiert. Das π‐konjugierte System expandierte von der Helicen‐Einheit zum BODIPY‐Gerüst, und die azahelicenkondensierten Borkomplexe zeigten die Cotton‐Effekte und eine deutlich zirkular polarisierte Lumineszenz (CPL) im sichtbaren Bereich.
