一般描述
应用
- Stable p-radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) adsorbed at the elbows of 22×3 reconstructed Au (111): This study focuses on the single-molecule level investigation of the stable organic radical DPPH, exploring its adsorption and interaction characteristics on a gold surface, which is crucial for understanding metal-free magnetic phenomena at subnanometer scales (R Vranik et al., 2020).
