galvinoxyl自由基的稳定性和磁化率被认为是铁磁性有机层行为的基础。然而，与galvinoxyl自由基的电子转移相关的磁响应仍然知之甚少。在这里，磁增强电子转移（MEET）从固定galvinoxyl自由基的新发现报告在电化学研究中使用galvinoxyl金电极。的电子转移速率常数增加了约78%，在1.32 mT的外部磁场的存在下相比，在没有磁场的情况下的电子转移速率。固体电极上有机自由基层的MEET也可能为开发新型铁磁纳米结构和器件开辟新的途径。
The stability and magnetic susceptibility of galvinoxyl radicals are believed to underpin the behaviour of ferromagnetic organic layers. However, the magnetic response associated with electron transfer from galvinoxyl radicals remains little understood. Here, new findings on magnetically-enhanced electron transfer (MEET) from immobilized galvinoxyl radicals are reported in an electrochemical study using galvinoxyl–gold electrodes. The electron transfer rate constant increases by about 78% in the presence of an external magnetic field of 1.32 mT compared to the electron transfer rate in the absence of a magnetic field. The MEET of organic radical layers on a solid electrode may also open up new avenues for the development of novel ferromagnetic nanostructures and devices.
