“Soft theories,” ie,“heuristic models based on reasoning by analogy” largely drove chemistry
understanding for 150 years or more. But soft theories have their limitations and with the …

Atomically precise graphene nanoribbons (GNRs) attract great interest because of their
highly tunable electronic, optical, and transport properties. However, on-surface synthesis of …

We discuss the past decade of progress in the field of photoremovable protecting groups
that allowed the development of photocages activatable by near-IR light and highlight the …

Controlling the electronic spin state in single molecules through an external stimulus is of
interest in developing devices for information technology, such as data storage and quantum …

We describe the synthesis and properties of 13, 14-dimethylcethrene, a prototype of a chiral
diradicaloid photochemical switch that can be transformed reversibly via conrotatory …

5, 14-Diaryldiindeno [2, 1-f: 1′, 2′-j] picene (DDP, 1), a thermally and chemically stable
helical arene, can be prepared from 1, 4-bis [2-(arylethynyl) phenyl] benzene in four …

The biradicaloid character of different types of polycyclic aromatic hydrocarbons (PAHs)
based on small band gaps is an important descriptor to assess their opto-electronic …

Atomically precise single-layer graphene fragments show size-and edge-dependent
electronic properties and are promising materials for electronics, photonics and spintronics …

Woodward and Hoffmann, in their treatise on orbital symmetry in 1969, stated “Violations.
There are none!” Prinzbach reported in 1978 that the electrocyclization of vinylogous …

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