Abstract

Abstract: Invited for this month's cover picture is a group of synthetic and physical chemists from the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences and J. Heyrovský Institute of Physical Chemistry of the Czech Academy of Sciences (Czech Republic). The cover picture shows folding of azoniahelicene by electron transfer.

Abstract : "Helquats containing seven‐membered rings substituted with redox‐active ethenylpyridinium in the α or γ position with respect to the nitrogen atoms of the helquat core yield tetra‐cationic derivatives. Reversible electron transfers switch the intensity of the electronic circular dichroism signal of both tetra‐cations. Derivatives substituted in the γ position during the electron transfer undergo structural folding…" Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
