Catalytic enantioselective synthesis of chiral helicenes and helicenoids has emerged as an
important area of research. In the efforts toward efficient and enantioselective synthesis of …

We disclose a series of silicon-bridged diazulenylmethyl cations as stable and one-
dimensionally π-extended carbocations. Connecting nonbenzenoid azulenes to a …

The chemistry of nonalternant hydrocarbons has recently experienced a considerable
resurgence. As the relationship between naphthalene and azulene shows, an important …

Incorporating non‐hexagonal rings into polycyclic conjugated hydrocarbons (PCHs) can
significantly affect their electronic and optoelectronic properties and chemical reactivities …

Chiral nanographenes with both high fluorescence quantum yields (ΦF) and large
dissymmetry factors (glum) are essential to the development of circularly polarized …

The precision synthesis of helical bilayer nanographenes (NGs) with new topology is of
substantial interest because of their exotic physicochemical properties. However, helical …

A modular approach to azulene building blocks was developed starting from readily
available aryl‐substituted cyclopentadiene and ortho‐haloaryl aldehyde by dehydration …

Azulene-based conjugated systems are of great interests due to their unusual structures and
photophysical properties. Incorporation of a transition metal into azulene skeleton presents …

It is essential to create organic compounds that exhibit circularly polarized luminescence
(CPL) in the near‐infrared (NIR) range. Helicene‐type emitters possess appealing …

We report here the one‐pot synthesis of benzo [1, 2‐a: 3, 4‐a′: 5, 6‐a′′] triazulene
(BTA), wherein three azulene units are embedded through a tandem reaction comprising …
