Helicenes consist of ortho-annulated aromatic and/or heteroaromatic rings endowed with a helical chirality.[1] Enantiopure helicenes can be isolated because of their stable and rigid helical conformation; furthermore, some of them form aggregates to give helical supramolecular architectures potentially applicable to nonlinear optics, electrooptic switches, and circularly polarized luminescent materials.[2] To expand the application of ...
