Conspectus Persistent radicals are potential building blocks of novel materials in many
fields. Recently, highly stable persistent radicals are considered to be within reach, thanks to …

Radicals are an important class of species which act as intermediates in numerous chemical
and biological processes. Most of the radicals have short lifetimes. However, radicals with …

Conspectus Nitric oxide (NO) is an endogenous signaling molecule that participates in
various physiological and biological pathways associated with vasodilation, immune …

Carbenes, including N‐heterocyclic carbene (NHC) ligands, are used extensively to
stabilize open‐shell transition metal complexes and organic radicals. Yet, it remains …

Nitric oxide (NO) is widely known as an effective vasodilator at low concentrations. Drug
delivery systems combined with NO can dilate blood vessels surrounding tumor tissues, and …

N-heterocyclic carbenes (NHCs) are recognized for their ability to stabilize various main
group radicals; however, NHC-derived, sulfur-based radicals remain rare. In this study, we …

Over the past decade, numerous stable organic and main‐group radicals have been
synthesized from N‐heterocyclic carbenes (NHCs). The structure of NHCs, in particular …
