Organic Polyradicals: Synthesis, Characterization and Application

Abstract

Organic polyradicals, a fascinating class of compounds characterized by the presence of multiple unpaired electrons, are gaining increased attention from researchers as potential materials in various scientific and technological fields due to their distinct redox-active properties. This critical review focuses on the synthesis and characterization of two distinct types, polymeric and large/macro molecular organic polyradicals. In addition, their applications in energy storage, catalysis, and biomedical sciences are outlined. Various synthetic strategies, including radical polymerization, post-polymerization modification, and template-assisted synthesis are explored. Subsequently, particular emphasis is given to the synthesis of conducting materials bearing stable radicals as an emerging class of functional materials with enhanced redox properties. This critical review essay underscores the potential of organic polyradicals as a versatile class of compounds for driving significant advancements in chemical science and technology.
