On-surface synthesis of planar acenes via regioselective aryl-aryl coupling

Abstract

The reaction of 2,2’-Dibromo-Biphenyl on a Ag(111) surface leads to the formation of planar acenes with a high-regioselectivity rather than nonplanar saddle-shaped tetraphenylene as the typical product in solution chemistry. The regioselective aryl-aryl coupling reaction is attributed to the hydrogen repulsion between the reactants on the confined two-dimensional surface.
