This review surveys recent progress in the chemistry of polycyclic heteroaromatic molecules
with a focus on structural diversity and synthetic methodology. The article covers literature …

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 …

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 …

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 …

Conspectus Aromaticity is one of the most important concepts in organic chemistry to
understand the electronic properties of cyclic π-conjugated molecules. Over a century …

Aromaticity is a vital concept that governs the electronic properties of π-conjugated organic
molecules and has long been restricted to 2D systems. The aromaticity in 3D π-conjugated …

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 …

Cycloarenes and heterocycloarenes display unique physical structures and hold great
potential as organic semiconductors. However, the synthesis of (hetero) cycloarenes …

Summary π-Conjugated molecules with an annulene-within-an-annulene (AWA) super-ring
structure have been pursued by chemists for a long time but with limited success. Here, we …

Higher order acenes (ie, acenes longer than pentacene) and extended zethrenes (ie,
zethrenes longer than zethrene) are theoretically predicted to have an open-shell singlet …
