Open-shell radicals are usually thermodynamically and kinetically unstable due to their
incompletely satisfied valency. However, the rapid development of radical chemistry in the …

This work provides an overview of the recent advances in the field of two-photon absorbing
chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein the …

Open-shell molecules such as radicals, carbenes, and electronically excited-state molecules
exhibit high energies, and thus, in general, they are quite reactive. 1 The short-lived species …

Sterically hindered C═ C double bonds often deform into a bent or twisted geometry. Thus,
many overcrowded ethylenes or anthraquinodimethanes can adopt multiple conformations …

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 …

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 …

The design and preparation of molecular systems with multiple geometric and electronic
configurations are the cornerstones for multifunctional materials with stimuli-responsive …

Organic molecules with unpaired electrons are intriguing for advanced applications in
molecular electronics, spintronics and organic batteries, as well as other possible …

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 …
