Rationally designed polyradical nanographenes with strong spin entanglement and perturbation resilience via Clar’s goblet extension (opens in new tab)

Polyradical nanographenes featuring strong spin entanglement and robust many-body spin states against external magnetic perturbations not only enable the exploration of correlated quantum magnetism at the molecular scale, but also constitute promising candidates for developing molecular qubits with chemical tunability and building scalable quantum networks. Here we use a predictive design strategy to realize the on-surface synthesis of two homologues of Clar’s goblet, C62H22 and C76H26, via l...
