More recently, alkyne terminated derivatives have started to play a role. Usually thiols and disulfides are chosen to covalently modify gold surfaces, including gold nanoparticles, with organic radicals by adsorption from solution. However, the radical functionalization of a substrate is eased by choosing a specific chemical group that has a high chemical affinity for the selected substrate. 9 Our work indicated the need for identifying strategies in order to attach the radical to the surface preserving its magnetic moment at the interface by using different methods ranging from evaporation to preparation in a wet environment. We have recently demonstrated that a Blatter radical derivative is a potential quantum bit and we attached it to copper contacts to investigate the influence of a substrate on the radical magnetic moment. 1–8 In this framework, organic radicals are exceptionally promising in various fields, and the research on radical thin films and interfaces has recently flourished, due to their potential use in applications from quantum computing to organic electronics and spintronics.
Molecular systems are materials that intersect with many different promising fields such as organic/molecular spintronics, electronics, and organic magnetism.
