Oxidative aromatic coupling occupies a fundamental place in the modern chemistry of
aromatic compounds. It is a method of choice for the assembly of large and bewildering …

Helicenes are attractive non-planar polycyclic aromatic hydrocarbons with unique optical
and electronic properties. In recent years, the chemistry of “multiple helicenes” with plural …

Herein, we report the synthesis, structural analysis, optical and chiroptical properties of a
novel quadruple helicene, which has two [6] and two [7] helicene moieties fused in a …

We report the synthesis and characterization of two hexapole [7] helicenes (H7Hs). Single
crystal X-ray diffraction unambiguously confirms the molecular structure. H7H absorbs light …

A one-step synthesis of a nanographene propeller with a D 3-symmetry was obtained
starting from 7, 8-dibromo [5] helicene by Yamamoto nickel (0) couplings. It afforded a chiral …

Optically active triple helicenes (TH-1) were prepared via a palladium-catalyzed
enantioselective cross-cyclotrimerization of two helicenyl arynes 5, which are generated in …

A series of hexapole helicenes (HHs) and nonuple helicenes (NHs) were prepared from 1,
3, 5-tris [2-(arylethynyl) phenyl] benzene through two steps, namely, iodocyclization and …

We report a molecular design and concept using π‐system elongation and steric effects from
helicenes surrounding a triphenylene core toward stable chiral polycyclic aromatic …

The synthesis of new carbazole‐fused polycyclic aromatics with interesting geometry and
useful properties was explored using Scholl reactions. As found from the Scholl reactions of …

Die oxidative aromatische Kupplung nimmt einen grundlegenden Platz in der modernen
Arenchemie ein. Sie ist das Mittel der Wahl für den Aufbau großer, komplizierter …
