The advent of spintronics has undoubtedly revolutionized data storage, processing, and sensing applications. Organic semiconductors (OSCs), characterized by long spin relaxation times (>μs) and abundant spin-dependent properties, have emerged as promising materials for advanced spintronic applications. To successfully implement spin-related functions in organic spintronic devices, the four fundamental processes of spin generation, transport, manipulation, and detection form the main building blocks and are commonly in demand. Thereinto, the effective generation of spin polarization in OSCs is a precondition, but in practice, this has not been an easy task. In this context, considerable efforts have been made on this topic, covering novel materials systems, spin-dependent theories, and device fabrication technologies. In this review, we underline recent advances in external spin injection and organic property-induced spin polarization, according to the distinction between the sources of spin polarization. We focused mainly on summarizing and discussing both the physical mechanism and representative research on spin generation in OSCs, especially for various spin injection methods, organic magnetic materials, the chiral-induced spin selectivity effect, and the spinterface effect. Finally, the challenges and prospects that allow this topic to continue to be dynamic were outlined.

Nanoscale Horizons
Nanoscale Horizons is a leading journal for the publication of exceptionally high-quality, innovative nanoscience and nanotechnology. The journal places an emphasis on original research that demonstrates a new concept or a new way of thinking (a conceptual advance), rather than primarily reporting technological improvements. However, outstanding articles featuring truly breakthrough developments such as record performance alone may also be published in the journal. For work to be published it must be of significant general interest to our community-spanning readership. Topics covered in the journal include, but are not limited to: Synthesis of nanostructured and nanoscale materials Quantum materials 2D materials Layered materials Layered quantum materials Characterisation of functional nanoscale materials and bio-assemblies Properties of nanoscale materials Self-assembly and molecular organisation Complex hybrid nanostructures Nanocomposites, nanoparticles, nanocrystalline materials, and nanoclusters Nanotubes, molecular nanowires and nanocrystals Molecular nanoscience Nanocatalysis Theoretical modelling Single-molecules Plasmonics Nanoelectronics and molecular electronics Nanophotonics Nanochips, nanosensors, nanofluidics and nanofabrication Carbon-based nanoscale materials and devices Biomimetic materials Nanobiotechnology/bionanomaterials Nanomedicine Regulatory approaches and risk assessment
