Tuning the Spin Interaction in Non-planar Organic Diradicals Through Mechanical Manipulation

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Alessio Vegliante, Saleta Fernandez, Ricardo Ortiz, Manuel Vilas-Varela, Thomas Baum | Summary: Open-shell polycyclic aromatic hydrocarbons (PAHs) represent promising building blocks for carbon-based functional magnetic materials. Their magnetic properties stem from the presence of unpaired electrons localized in radical states of $pi$ character. […]
