Abstract

The magnetic and structural properties of an organic film, composed of a β-diketonato complex functionalized with iodine atoms (C30H18CuI4O4), deposited on a graphite surface are probed using synchrotron radiation spectroscopies and scanning tunneling microscopy. The Cu2+ complexes form a halogen-bonded network at the interface, and the molecules in the film preferentially remain parallel to the graphite surface. For a temperature of 2 K, the complex film is paramagnetic; no preferential easy axis of magnetization is detected. The engineering and characterization of organic films composed of molecular magnets is essential for developing novel applications in spintronics and nanomagnetism due to the appealing magnetic and electronic properties of these materials.

石墨表面I···I相互作用稳定的铜β-双酮ato配合物膜在2k下的磁性增强
利用同步辐射光谱和扫描隧道显微镜研究了沉积在石墨表面的由碘原子功能化的β-双酮酸配合物(C30H18CuI4O4)组成的有机薄膜的磁性和结构性质。Cu2+配合物在界面处形成卤素键合网络,膜中的分子优先保持与石墨表面平行。当温度为2k时,络合膜呈顺磁性;没有检测到优先易磁化轴。分子磁体组成的有机薄膜的工程和表征对于开发自旋电子学和纳米磁学的新应用至关重要,因为这些材料具有吸引人的磁性和电子特性。
