Spintronic Optoelectronic Effects and Material Developments of Organic Semiconductors
Organic semiconductors have exhibited not only excellent optoelectronic properties, but also many unique advantages such as lightweight, flexibility, easy processability, and low cost. In recent years, the introduction of the 'spin' as a new degree of freedom into organic semiconductors expands the research of organic optoelectronic effects and material studies into new dimensions, providing novel approaches for developing new materials, regulating new functionalities, and designing innovative devices. This article systematically reviews recent progress in spin-related research of organic semiconductors, thoroughly exploring the injection, transport, and relaxation mechanisms of spin-polarized electrons. It introduces various organic spintronic devices and their underlying physical principles, comprehensively summarizes different types of organic spin-semiconductor materials including small molecules, polymers, exciplexes, and organic/inorganic hybrids, along with their applications in devices such as spin valves, spin light-emitting diodes, spin photovoltaic devices, and spin field-effect transistors. Finally, we provide perspectives on future development directions in organic spintronics, aiming to offer valuable references for subsequent in-depth research in this perspective investigation field.
