The past decade has witnessed remarkable success in the synthesis of curved polycyclic
aromatics through Scholl reactions which enable oxidative aryl–aryl coupling even in …

Helicenes have attracted considerable attention due to their inherent helical chirality and
extended π-conjugation. Recently, rapid progress has been witnessed in the preparation of …

An expanded heterohelicene consisting of three BN2-embedded [4] helicene subunits (V-
DABNA-Mes) has been synthesized by one-shot triple borylation. The key to success is the …

Nanographenes, or extended polycyclic aromatic hydrocarbons, have been attracting
renewed and more widespread attention since the first experimental demonstration of …

Oxidative aromatic coupling occupies a fundamental place in the modern chemistry of
aromatic compounds. It is a method of choice for the assembly of large and bewildering …

Conspectus Negatively curved carbons are theoretical carbon allotropes as proposed by
embedding heptagons or octagons in a graphitic lattice. Unlike five-membered rings in …

Does the dehydrogenative coupling of aromatic compounds mediated by AlCl3 at high
temperatures and also by FeCl3, MoCl5, PIFA, or K3 [Fe (CN) 6] at room temperature …

Expanded carbohelicenes with structures fused to 15-and 17-benzene were successfully
synthesized. Establishing a new synthetic strategy is crucial to realize the development of …

Carbon nanobelts that consist of a loop of fully fused benzene rings are long-standing and
challenging targets of organic synthesis and are key steps toward the ultimate synthesis of …

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