Title: Synthesizing carbon nanothreads from benzene

Carbon nanomaterials—e.g., fullerenes, nanotubes, and graphene, with dimensionalities of 0, 1, and 2, respectively—possess beautiful chemical bonding arrangements and extraordinary physical and chemical properties:1–3 see Figure 1(a). As is the case with graphite, their carbon atoms are bonded to three neighbors. Diamondoid molecules and graphane (the fully hydrogenated form of graphene) have fourfold tetrahedral bonding (like diamond) and dimensionalities of 0 and 2, respectively: see Figure 1(b). The diamondoid molecule adamantane, which is capped by hydrogen atoms, comprises the smallest unit cage structure of the diamond crystal lattice. Similarly, graphane represents the thinnest possible sheet of diamond. In this context, queries arise regarding what form the thinnest possible 1D diamond thread would take.
