Engineering 2D spin networks by on-surface encapsulation of azafullerene radicals in nanotemplates by Gregor Kladnik, Luca Schio, Gregor Bavdek, Yuri Tanuma, Marion van Midden Mavrič, Erik Zupanič, Bastien Anézo, Ioanna K. Sideri, Nikos Tagmatarchis, Jannis Volkmann, Hermann A. Wegner, Andrea Goldoni, Christopher P. Ewels, Alberto Morgante, Luca Floreano, Denis Arčon, Dean Cvetko

“…By vacuum deposition of azafullerene (C59N•) monomers on a pre-deposited template layer of [10]cycloparaphenylene ([10]CPP) nanohoops on Au(111) surface we exploit the molecular shape matching between the C59N• and [10]CPP for the azafullerene encapsulation with nanohoops in a guest-host complexation geometry. C59N•⊂[10]CPP supramolecular complexes self-assemble into an extended two-dimensional hexagonal lattice yielding a high density network of stable spin-1/2 radicals. …”
