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 Researchers have studied polycyclic aromatic hydrocarbons (PAHs) for more
than 100 years, and most PAHs in the neutral state reported so far have a closed-shell …

Organic diradicaloids have unique open-shell structures and properties and promising
applications in organic electronics and spintronics. Incorporation of heteroatoms is an …

The consequence of unpaired electrons in organic molecules has fascinated and
confounded chemists for over a century. The study of open-shell molecules has been …

In this Feature Article, we highlight our recent efforts toward stable open-shell singlet
diradicaloids and polyradicaloids. A brief review on the historical works in the area is …

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

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

Molecular nanocarbons containing heptagonal rings have attracted increasing interest due
to their dynamic behavior, electronic properties, aromaticity, and solid‐state packing …

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

Heterocyclic diradicaloids with atom‐precise control over open‐shell nature are promising
materials for organic electronics and spintronics. Herein, we disclose quinoidal π‐extension …
