Abstract

Helicenes are nonplanar ortho-fused aromatic compounds with helical chirality.[1] Their extraordinary optical and electronic properties have been of interest for a long time.[2] During the last decade, studies have been carried out toward their application in asymmetric synthesis,[3] molecular recognition,[4] and materials science, for example, as liquid crystals, sensors, and dyes.[5]
