The zero-field, low-energy spectrum of recently realized isotropic spin chains could be explained by a family of exactly solvable models and is expect…

Communications Chemistry, Published online: 03 December 2025; doi:10.1038/s42004-025-01701-0Understanding cycloaddition mechanisms is beneficial for the creation of extended carbon nanostructures, yet traditional models often overlook symmetry-based mechanistic effects. Here, the authors employ topological classifiers to identify symmetry-forbidden pathways in polycyclic aromatic azomethine ylide cycloadditions, revealing that topologically-allowed endothermic reactions can guide nanographene engineering.

Graphene nanostructures with π magnetism offer a chemically tunable platform to explore correlated magnetic interactions. Here, the on-surface synthesis of spin-1/2 antiferromagnetic Heisenberg chains...
