Aromaticity is an important concept to understand the stability and physical properties of π-
conjugated molecules. Recent studies on pro-aromatic and anti-aromatic molecules …

Conspectus Highly conjugated hydrocarbons have attracted interest for use as active
materials in electronic devices such as organic field effect transistors (OFET) and organic …

Abstract Azulene 1, pentalene 2, and heptalene 3 are classical nonalternant hydrocarbons.
Their fascinating π-frameworks, consecutive arrangements of odd-membered carbocycles …

Elusive nature in spin state is a feature of singlet biradical molecules and arises from the
weak coupling of unpaired electrons. This highlight review focuses on recent advances in …

The unique open-shell electronic structure of neutral π-radicals has inspired research on
novel molecular materials for over a century. In recent years, rapid development in carbon …

The study of low-energy light-absorbing molecules based on a topological alignment design
for conjugated π electrons in organic molecules has attracted much interest in connection …

Defects have been observed in graphene and are expected to play a key role in its optical,
electronic, and magnetic properties. However, because most of the studies focused on the …

Diradicaloid helicenes constructed formally by non‐benzenoid double π‐extension of
phenanthrene were synthesized by a common strategy involving double electrophilic …

We report the on-surface synthesis of a nonbenzenoid triradical through dehydrogenation of
truxene (C27H18) on coinage metal and insulator surfaces. Voltage pulses applied via the …

Inclusion of quinoidal cores in conjugated hydrocarbons is a common strategy to modulate
the properties of diradicaloids formed by aromaticity recovery within the quinoidal unit. Here …
