Question

These materials can be suspended by wrapping them in poly(arylene-ethylene) in a method that affords a relatively consistent pitch length. These materials can be oxidized to create “peapods,” which can then be annealed to create a different type of these materials. These materials are described by 2D vectors (n, m) (15[1])(“n-comma-m”) that count units on a lattice; if 2n plus m is a multiple of three, then these materials are metallic. These materials were first synthesized by Iijima (“ee-ee-JEE-mah”) using the (*) arc-discharge method and come in (10[1])chiral, zigzag, and armchair forms. Multi-walled (10[1])examples of these structures are comprised of nested single-walled versions of them, which can act as extremely strong fibers. For 10 points, name these carbon allotropes with a (10[1])cylindrical structure (10[1])resembling (10[1])a rolled-up sheet of graphene. ■END■ (10[2])
