Influence of the intra- and intermolecular hydrogen bonds on the redox properties of aminoanthraquinone derivatives

摘要

Non-covalent interactions play a critical role in mediating a range of biological electron-transfer (ET) processes.While subject to considerable theoretical and experimental scrutiny,the fundamental principles of how such interactions might serve to modulate ET reactions remain recondite.Quinones are very important redox species that have played an important role in organic chemistry,electrochemistry,and other fields,including biochemistry where quinones take part in important processes such as respiration and photosynthesis.For this reason we have chosen to study simple model systems that would allow the underlying chemical and electrochemical events to be probed with precision.In this context,particular attention has been focused on chemical systems exhibiting intramolecular and intermolecular hydrogen bonding.
