Topological classification of cycloadditions occurring on-surface and in the solid-state

Communications Chemistry
The study of cycloaddition mechanisms is central to the fabrication of extended sp 2 carbon nanostructures such as graphene nanoribbons and spin chains. Reaction modeling in this context has focused mostly on putative, energetically preferred, exothermic
