Deskripsi

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.
