Reticular Growth of Graphene Nanoribbon 2D Covalent Organic Frameworks
Abstract
Fischer and co-workers present the realization of a porous crystalline two dimensional (2D) covalent organic framework (COF) grown from a polydisperse macromolecular building block. Bottom-up synthesized graphene nanoribbons (GNRs), quasi-one-dimensional (1D) atomically defined strips of single-layer graphene, self-assemble at a liquid-liquid interface into π-stacked 2D sheets cross-linked by diamine spacers. This distinct class of infinitely tunable 2D layered materials is anticipated to give rise to correlated phenomena emerging from the intrinsic anisotropy of constituent 1D GNR building blocks.
