Chiroptical switches, whose chiral optical signals such as optical rotatory dispersion (ORD),
circular dichroism (CD) and circularly polarized luminescence (CPL) are reversibly …

In this review, we discuss the rich chemistry of helicenes and helicenoids containing main-
group elements. Enantioenriched helicenic derivatives containing main-group elements B …

Prompted by the recent rapid growth of interest in circularly polarized luminescence (CPL) of
organic molecules, we have collected all the reliable CPL, as well as the corresponding …

Straightforward synthesis and resolution of a series of chiral fluorescent macrocycles are
presented, together with their electronic circular dichroism (ECD), strong excimer …

Chiral molecules exist as pairs of nonsuperimposable mirror images; a fundamental
symmetry property vastly underexplored in organic electronic devices. Here, we show that …

Abstract Deep Eutectic Solvents (DESs) offer advantages similar to ionic liquid (IL) ones,
with easier and more sustainable synthesis; moreover, bio-based DESs often include chiral …

Overcrowded alkenes have received considerable attention as versatile structural motifs in a
range of optical switches and light-driven unidirectional motors. In contrast, their actuation by …

Oxidative fusion reaction of cyclic heteroaromatic pentads consisting of pyrrole and
thiophene gave closed‐heterohelicene monomers and dimers depending on the oxidation …

Herein, we report a convergent synthesis of 1-azahelicenes using easily available quinoline
derivatives and cyclic diaryliodonium salts as starting materials. This reaction undergoes a …

The synthesis of [6] helicene para-quinone starting from the 1, 4-dimethoxy-[6] helicene
derivative is presented. The demethylation reaction with boron tribromide led to unexpected …
