Architecture and properties of a novel two-dimensional carbon material-graphtetrayne

A novel 2D carbon allotrope-Graphtetrayne (GTY), features four acetylene linkages between the pairs of benzene rings to form 30-C hexagons was synthesized by a facile synthesized route of Sonagashira cross-coupling reaction of hexaethynylbenzene and diiodobutadiyne. This all-carbon material shows a distinct structural feature, rich triple bonds and super large cavities structures, which not only has high chemical activity, but also show the high...
