Dissociative Ligand Field-Based Photochemistry in Organometallic Compounds

Abstract

The dissociation of ligands by excitation of coordination complexes with visible and UV light is a field that is now over 100 years old, yet it is increasingly relevant due to the opportunities it provides for applications from photoinduced anionic polymerization and biomedical applications, for example, to release small molecules (CO, NO, etc.) of relevance to signaling or to release/activate drugs. In this chapter we will focus on the release of small molecules (primarily amine, CO and arene) with paradigms of the main classes of photochemically induced ligand dissociation. The discussion will focus on the processes themselves and not applications.
