Helquats: Chemistry of Helicene-Viologen Hybrids
Abstract: Viologens and helicenes have been in focus of many research laboratories
due to their attractive and rich chemistry. This interest centers mainly around
electrochemistry, supramolecular self assembly, optical properties, chirality, and
catalysis. In our recent reports we introduced helquats which represent a structural
link between helicenes and viologens (see scheme and references). Our efforts have
been driven by a hypothesis that crossbreeding the two widely known and privileged
compound classes will generate interesting and useful knowledge. Helquat chemistry
will be discussed from the point of view of our current synthetic and stereochemical
studies.
