As cut-outs from a graphene sheet, nanographenes (NGs) and graphene nanoribbons
(GNRs) are ideal cases with which to connect the world of molecules with that of bulk carbon …

Helical bilayer nanographenes (HBNGs) are chiral π-extended aromatic compounds
consisting of two π–π stacked hexabenzocoronenes (HBCs) joined by a helicene, thus …

Polycyclic aromatic hydrocarbons (PAHs) as a typical class of organic semiconductors
demonstrate unique optical, electrical, magnetic and other interesting properties due to their …

Chirality is one of the most intriguing concepts of chemistry, involving living systems and,
more recently, materials science. In particular, the bottom-up synthesis of molecular …

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

Polycyclic aromatic hydrocarbons (PAHs) have been the subject of interdisciplinary research

Here we report the synthesis of two polyhelicene frameworks consisting, from end-to-end, of
18 and 24 fused benzene rings. The latter exhibits the largest electronic circular dichroism in …

Twisted carbon nanobelts could display persistent chirality, which is desirable for material
applications, but their synthesis is very challenging. Herein, we report the successful …

Azulene is a non‐benzenoid aromatic building block with unique chemical structure and
physicochemical properties. By using the “bottom‐up” synthetic strategy, we synthesized …
