Organic semiconductors can be designed and constructed in π‐stacked structures instead of
the conventional π‐conjugated structures. Through‐space interaction (TSI) occurs in π …

We give an overview of the molecular response to an external magnetic field perturbing
quantum mechanical systems. We present state-of-the-art methods for calculating …

Several fully π-conjugated macrocycles with puckered or cage-type structures were recently
found to exhibit aromatic character according to both experiments and computations. We …

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

A π-conjugated molecule with one electronic spin often forms a π-stacked dimer through
molecular orbital interactions between two unpaired electrons. The bonding is recognized …

Three-dimensional aromaticity arising from the close stacking of two antiaromatic π-
conjugated macrocycles has recently received considerable attention. Here, a cyclophane …

An olympicenyl radical, a spin 1/2 hydrocarbon radical with C 2 v symmetry and uneven spin
distribution, remains elusive despite the considerable theoretical research interest. Herein …

Face-to-face stacking of aromatic compounds leads to stacked antiaromaticity, while that of
antiaromatic compounds leads to stacked aromaticity. This is a prediction with a long history; …

Stacked-ring aromaticity arising from the close stacking of antiaromatic π-systems has
recently received considerable attention. Here, we realize stacked-ring aromaticity via a …

Recent studies have theoretically and experimentally demonstrated that antiaromatic
molecules with 4n π electrons exhibit stacked aromaticity according to π–π stacking when …
