“…Inspired by these ideas, we pioneered the controlled growth of organic radical thin films and we introduced the use of soft X-rays to investigate this class of materials. , Materials with a radical site, i.e., with one or more unpaired electrons that give rise to a permanent magnetic moment, − are strong candidates for ground-breaking applications, − because of low-cost, energy saving technologies and eco-friendly production, holding the promise of social impact. ,− While the function and performance of devices are highly important, the material stability also needs to be addressed if these technologies are to find their way to industrial applications. In this respect, we chose chemically stable organic radicals to grow thin films.…”

Blatter radical derivatives are very attractive due to their potential applications, ranging from batteries to quantum technologies. In this work, we focus on the latest insights regarding the fundamental mechanisms of radical thin film (long-term) degradation, by comparing two Blatter radical derivatives. We find that the interaction with different contaminants (such as atomic H, Ar, N, and O and molecular H2, N2, O2, H2O, and NH2) affects the chemical and magnetic properties of the thin films upon air exposure. Also, the radical-specific site, where the contaminant interaction takes place, plays a role. Atomic H and NH2 are detrimental to the magnetic properties of Blatter radicals, while the presence of molecular water influences more specifically the magnetic properties of the diradical thin films, and it is believed to be the major cause of the shorter diradical thin film lifetime in air.
