Two-dimensional materials

Polymers stripped down

Two-dimensional polymers can serve to organize chemical functionality periodically over large areas, but their rational synthesis has remained limited. Now, a free-standing, single-layer polymer sheet has been prepared and isolated through a two-step procedure — a photochemical reaction within a layered organic crystal followed by exfoliation.
