Conspectus Polycyclic (hetero) aromatic hydrocarbons (PAHs) have emerged as a focal
point in current interdisciplinary research, spanning the realms of chemistry, physics, and …

Open-shell systems with extensive π-conjugation have fascinating properties due to their
narrow bandgaps and spin interactions. In this work, we report neutral open-shell di-and …

Selective and site-specific boron-doping of polycyclic aromatic hydrocarbon frameworks
often give rise to redox and/or photophysical properties that are not easily accessible with …

We begin by reviewing the early developments in the synthesis of high-spin organic
molecules and the simultaneous rationalization of the ground states of high spin. A number …

The diradical character in a molecular architecture can be customized primarily in two ways:
first, by employing a quinoidal pro-aromatic system with net energy gained by aromatization …

Although Bu3Sn-mediated radical alkyne peri-annulations allow access to phenalenyl ring
systems, the oxidative termination of these cascades provides only a limited selection of the …

A convenient design strategy opens access to neutral open-shell mixed-valence species via
the redox transformation of charged stable precursors, ie, the spiro-fused borate anions. We …

A computational study (ωB97X-D/6-31G (d)) of the Mallory photocyclization reaction has
revealed that the well-established dihydrophenanthrene (DHP) intermediates can adopt …

Unique spin–spin (magnetic) interactions, ring‐size effects on ground‐state spin multiplicity,
and in‐plane aromaticity has been found in localized 1, 3‐diradicals embedded in curved …

This work addresses a class of conjugated hydrocarbons that are expected to be singlet
diradicals according to the topological Hückel Hamiltonian while possibly satisfying full on …
