Graphene is a 2D giant polycyclic aromatic molecule that provides opportunities for studying chemical reactions in two dimensions. H. Peng, Z. Liu, and co-workers have systematically investigated the influence of specific features of 2D molecules, such as their thickness, stacking order, single- and double-side upon graphene's radical reactivity by utilizing a free radical photochlorination as a probe. The result, described on page 1388, can contribute to a deeper understanding of dimensionality effects for the chemistry of 2D graphene.
