Fast atom bombardment (FAB) mass and MS/MS spectra of a novel quinone antibiotic are presented. Their interpretation is based upon the examination of reductive behavior of model quinones in FAB solvents.

New anthraquinone derivatives were prepared and used as active layers of organic field-effect transistors (OFETs); these devices showed good n-type characteristics and the quinones were found to be useful for organic semiconductors in OFETs.

The 1,4-benzoquinone moiety is a common structural feature in a large number of compounds that have received considerable attention owing to their broad spectrum of biological activities. The cytotoxic and antiproliferative properties of many natural sesquiterpene quinones and hydroquinones from sponges of the order Dictyoceratida, such as avarol, avarone, illimaquinone, nakijiquinone and bolin...

In recent years, there has been considerable interest in the potential of quinones as a promising category electroactive species for use aqueous organic redox flow batteries. These materials offer tunable properties and ability to function both positive negative electrolytes, making them highly versatile suitable range applications. Ongoing research focused on improving stability, solubility, p...

Quinones feature prominently as electron acceptors in nature. Their electron-transfer reactions are often highly exergonic, for which Marcus theory predicts reduced electron-transfer rates because of a free-energy barrier that occurs in the inverted region. However, the electron-transfer kinetics that involve quinones can appear barrierless. Here, we consider the intrinsic properties of the par...
