The synthesis and isolation of a nitrogen-embedded polycyclic compound with strong antiaromaticity and stability was achieved for the first time by a research group at Ehime University. This result ...

Organic chemistry features a wide array of reactions for creating complex molecules, among which the Diels–Alder reaction stands out for its versatility and precision. This reaction enables the ...

THE epitaxial growth of thin crystalline films vacuum evaporated on a surface of single crystal is a very common phenomenon nowadays. However, the materials used so far have been mostly restricted ...

Spiroaspertrione A is a complex polycyclic compound naturally produced by the fungus Aspergillus sp. TJ23. First isolated in 2017, it quickly drew scientific attention for its promising ability to ...

Polycyclic aromatic hydrocarbons are an important class of fused-ring natural compounds that are under fire for being toxic. Evidence suggests PAHs, which occur naturally in oil (including edible oils ...

Complex polycylic structures are found in nearly every biosynthetic class of natural products. In particular, an amazing range of rigid densely functionalized polycylic compounds are formed from ...

Although this compound is a polycyclic aromatic hydrocarbon, severe intramolecular steric interactions force the anthracene nucleus to be greatly distorted from planarity, with an end-to-end twist of ...

Proceedings of the Royal Society of London. Series B, Biological Sciences, Vol. 121, No. 821 (Sep. 1, 1936), pp. 133-141 (9 pages) ...

Scientists in Korea have found cancer-causing polycyclic aromatic hydrocarbons in foods, highlighting the risks inherent with ...

Big, schmancy compounds keep popping up all over the solar system, and new research may help clear up confusion about how they form in so many places. That research is based on laboratory experiments ...
