Persistent radicals can hold their unpaired electrons even under conditions where they
accumulate, leading to the unique characteristics of radical ensembles with open-shell …

In the last few years, air‐stable organic radicals and radical polymers have attracted
tremendous attention due to their outstanding performance in flexible electronic devices …

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

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 …

Organic radicals can potentially play important roles in functional materials owing to an
unpaired electron, but they are usually highly reactive and difficult to use. Therefore …

While viologen derivatives have long been known for electrochromism and photochromism,
here we demonstrated that a viologen-carboxylate zwitterionic molecule in the crystalline …

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 …

Conspectus Porous frameworks possess high porosity and adjustable functions. The two
features conjointly create sufficient interfaces for matter exchange and energy transfer within …

Singlet diradicaloids hold great potential as semiconductors for organic field‐effect
transistors (OFETs). However, their relative low material and device stabilities impede the …

An olympicenyl radical, a spin 1/2 hydrocarbon radical with C 2 v symmetry and uneven spin
distribution, remains elusive despite the considerable theoretical research interest. Herein …
