Achieving high-performance room-temperature organic ferromagnetic semiconductor films via topochemical reduction (opens in new tab)

The development of high-performance organic ferromagnetic semiconductors has been hampered by the intrinsic coupling of radical formation and structural organization during synthesis, which makes it difficult to achieve long-range magnetic coupling in highly conjugated systems. Here, we report an effective topochemical reduction strategy that decouples radical formation from structural organization, enabling unprecedented control over intermolecular arrangements in organic ferromagnetic mater...
