N1 - Funding Information:
We thank all the current and former Casu and Rajca co-workers who contributed to the research on the thin films of Blatter radicals and whose names appear in the references, and in particular Tobias Junghoefer, Francesca Ciccullo, Nolan M. Gallagher, Shuyang Zhang, Chan Shu, Elke Nadler, Drs Suchada Rajca and Hui Zhang. Our special thanks go to Dr Maren Pink who helped us to characterize structurally the Blatter radicals. We would like to thank Helmholtz-Zentrum Berlin (HZB) for providing beamtime at BESSY II (Berlin, Germany) that allowed us to assess the structural properties of the thin films, Erika Giangrisostomi and Ruslan Ovsyannikov for their support at the beamline. The authors also thank Prof. T. Chasséfor the access to the photoelectron spectroscopy lab at the University of Tübingen. Financial support from the German Research Foundation (DFG) under the contract CA852/11-1 is gratefully acknowledged. We thank the National Science Foundation (NSF), Chemistry Division, for support of this research under Grants CHE-1665256 and CHE-1955349 (A.R.).

N2 - We demonstrate the possibility to evaporate Blatter radical derivatives in a controlled environment obtaining thin films that preserve the (poly)radical magnetic character. However, their thermal evaporation is challenging. We analyse the evaporation process and the thin film formation using thermodynamic concepts and describe the material properties also using first principles calculations. The presence of more than one radical site makes the radical more reactive, narrowing the windows left for evaporation, thus, favouring the assembly of molecules and island formation rather than two-dimensional growth.
