Abstract

Helicenes can be recognized as helical-shaped π-conjugated molecular structures composed of sequential ortho annulated aromatic rings with thermal stability and intrinsic chirality. Helicenes are generally characterized by their distinctive supramolecular structural design and unusual optical characteristics. Helicenes have been utilized on a broad range of potential applications, such as liquid crystals, material dyes, asymmetric synthesis, molecular switches, polymers, and photorefractive materials, nanomaterials via self-assembly, biological recognition, as well as photovoltaics, and light-emitting devices.
