Helquats: Helicene-Viologen Hybrids as a Novel Object of Chemical Research
Institute of Organic Chemistry and Biochemistry, Academy of Sciences of the Czech Republic, Prague
Helquats are novel helical dications combining features of two privileged classes of compounds helicenes and viologens. This review discusses the origin and current status of helquat chemistry focusing on three- and four-step synthetic routes. Driving forces in this freshly opened territory are the prospects of versatile applications inspired by chemistries of both viologens and helicenes. These novel chemical compounds are readily accessible.
