20.500.12556/RUL-166363 Engineering 2D spin networks by on-surface encapsulation of azafullerene radicals in nanotemplates We present an efficient strategy for on-surface engineering of organic metal-free supramolecular complexes with long-term spin protection. By vacuum deposition of azafullerene (C$_{59}$N$^•$) 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 C$_{59}$N$^•$ and [10]CPP for the azafullerene encapsulation with nanohoops in a guest-host complexation geometry. C$_{59}$N$^•$$\subset$[10]CPP supramolecular complexes self-assemble into an extended two-dimensional hexagonal lattice yielding a high density network of stable spin-1/2 radicals. We find compelling evidence for electronic coupling between the guest C$_{59}$N$^•$ and the host [10]CPP in supramolecular species. At the same time, [10]CPP effectively protects the radical state of encapsulated azafullerenes against dimerization and inhibits C$_{59}$N$^•$ coupling to the Au substrate. Azafullerene encapsulation by nanohoops represents a viable realization of molecular spin protection while simultaneously demonstrating exceptional self-assembling properties by which large-scale 2D architectures of molecular spins can be realized. physical chemistry electron transfer electronic properties and materials electronic structure of atoms and molecules qubits spintronics fizikalna kemija true false true Angleški jezik Slovenski jezik Članek v reviji 2025-01-08 15:35:38 2025-01-08 15:35:39 2025-11-25 12:14:41 0000-00-00 00:00:00 2025 0 0 10 str. art. 193 Vol. 16 Jan. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 544 2041-1723 10.1038/s41467-024-55521-2 221416707 s41467-024-55521-2.pdf s41467-024-55521-2.pdf 1 118CF2095B0306F31A51F34AFA4D9366 3dd370f53aafc3eb70432dee72473daf0cbda6edbb317ad67477cbd229041649 3a20efe8-cdd0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197935 https://www.nature.com/articles/s41467-024-55521-2 0 29fe9aa2-cdd0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197934 Fakulteta za matematiko in fiziko Pedagoška fakulteta 0 0 0
