Photochromism is defined as a reversible transformation of a chemical species between two
isomers having different absorption spectra induced in one or both directions by …

Helicenes are polycyclic aromatic compounds with nonplanar screw-shaped skeletons
formed by ortho-fused benzene or other aromatic rings. 1, 2 The first helicenes 1 and 2 …

Carbohelicenes are a class of fascinating chiral helical molecules which have a rich history
in chemistry. Over a period of almost 100 years, chemists have developed many methods to …

This Review discusses the structure–property relationships in chiral molecules,
macromolecules (polymers), and supramolecules (crystals, liquid crystals, or thin films) …

Helicenes are molecules with ortho-fused aromatic rings that adopt an inherently chiral
helical shape. This helical topology combined with the extended π-conjugated system …

Here we unveil a chiral molecular redox switch derived from PDI-based twistacenes─ c
hPDI [2] that has the remarkable attributes of high-intensity and a broadband chiral …

We describe the synthesis and properties of 13, 14-dimethylcethrene, a prototype of a chiral
diradicaloid photochemical switch that can be transformed reversibly via conrotatory …

In this work, the racemate and mesomer of the thiophene-based naphthalene-cored double
helicenes (1) were obtained efficiently by one-pot photocyclization of 1, 1, 2, 2-tetrakis …

A diarylethene possessing one [4] thiaheterohelicene and one benzothiophene, the latter
with a chiral methoxymethoxyethyl group on its C-3 position, was proved to work as a switch …

A photoresponsive diarylethene was incorporated in an achiral helical foldamer container. A
carbohydrate guest was found to induce opposite handedness upon binding to the open …
