A Carbazole‐Centered Expanded Helicene Stabilized with Hexabenzocoronene (HBC) Units

The synthesis and stabilization of heteroatom-doped nanocarbon molecules, such as carbazole-containing (super)helicenes, present significant challenges due to the complexities involved in maintaining structural integrity and electronic functionality. In this study, we successfully synthesized a carbazole-centered expanded tris-hexabenzo[7]helicene (1) via a facile FeCl
