This Review surveys the experimental and synthetic history of three classic antiaromatic
cores: cyclobutadiene, borole, and pentalene. The coverage extends from the bare …

Despite their inherent instability, 4 n π systems have recently received significant attention
due to their unique optical and electronic properties. In dibenzopentalene (DBP) …

π-Conjugated organic molecules have exciting applications as materials for batteries, solar
cells, light-emitting diodes, etc. Among these systems, antiaromatic compounds are of …

Experimental and theoretical rationalization of bond-shift valence tautomerization,
characterized by double-well potential surfaces, is one of the most challenging topics of …

Antiaromatic moieties fused in polycyclic π-conjugated molecules usually exhibit strong
localized antiaromaticiy. Herein, we reported the synthesis and properties of a …

In this study, we investigate a set of organic diradical structures in which two oxo-verdazyl
radicals are selected as radical spin centers that are connected (coupled) via six coupler …

Fully-organic molecules with high-spin ground states are promising building blocks for new
lightweight flexible magnetic materials for emerging technological applications (eg …

An approach to modulating the properties of carbon nanorings by incorporating pyrrolo [3, 2‐
b] pyrrole units is of particular interest due to the combined effect of heteroatom and …

Pentalenes are formally eight-π-electron antiaromatic, but π-expanded pentalenes can
display varying levels of paratropicity depending on the choice of annelated (hetero) arenes …

Reaction of the imidazolium‐stabilized diphosphete‐diide IDP with trityl phosphaalkyne
affords a mixture which contains the molecules 1 a and 1 b with a central C3P3 core, which …
