Neutral 1-boraphenalene displays the isoelectronic structure of the phenalenyl carbocation
and is expected to behave as an attractive organoboron multi-redox system. However, the …

Organic chemistry has developed rapidly as a carbon‐based science. Particularly,
hydrocarbons with aromatic rings have attracted much attention as molecular materials for …

Chichibabin's hydrocarbon and viologens are among the most famous diradicaloids and
organic redox systems, respectively. However, each has its own disadvantages: the …

Molecular chains of two-coordinate carbon atoms (cumulenes) have long been targeted,
due to interest in the electronic structure and applications of extended π-systems, and their …

The pursuit of di-coordinate boron radical has been continued for more than a half century,
and their stabilization and structural characterization remains a challenge. Here we report …

Distonic radical cations (DRCs) with spatially separated charge and radical sites are
expected to show both radical and cationic reactivity at different sites within one molecule …

Our study unveils a novel approach to accessing boryl radicals through the spontaneous
homolytic cleavage of B–B bonds. We synthesized a hexaaryl-substituted diboron (6) …

Abstract Thiele's Hydrocarbons (THs) featuring a 9, 10‐anthrylene core with switchable
geometric and electronic configurations offer exciting possibilities in advanced functional …

An extended class of organic multi‐redox systems was derived from bicyclic (alkyl) amino
carbenes (BICAACs). The highly‐conjugated system undergoes a total of 4 redox events …

Most redox systems generally cannot avoid the involvement of open‐shell species upon
generating multiply charged species, which often reduces reversibility in multi‐color …
