Graphene and fullerenes

The same element can form a single layer, a hollow sphere or a long hollow cylinder.

What you need to know

  • Graphene is a single layer of graphite, and its structure and bonding give it useful properties.
  • Fullerenes are hollow carbon molecules based on rings, mainly hexagonal but sometimes containing five- or seven-carbon rings.
  • Buckminsterfullerene, C60, is spherical, while carbon nanotubes are cylindrical fullerenes with very high length to diameter ratios.
  • Graphene and carbon nanotubes have useful applications, and their structures should be recognisable from diagrams and descriptions.

The big picture

Graphene is a single layer of graphite, and its structure and bonding give it properties useful in electronics and composites. Fullerenes are hollow molecules made from carbon atoms, with structures based on hexagonal rings that can also include rings of five or seven carbon atoms. Buckminsterfullerene, C60, is spherical, while carbon nanotubes are cylindrical fullerenes with very high length to diameter ratios. Recognising these different carbon structures helps you connect their shapes and bonding to their uses.

TONIGHT'S REVISION

Graphene and fullerenes

Learn to recognise carbon as a single layer, hollow sphere or long cylindrical fullerene.

Start with the shape

GraphenevsFullerenes

Use structure first: it is the fastest way to separate graphene from fullerenes.

Focus

A single layer of graphite

Fullerenes

Hollow molecules of carbon atoms

The insight

Graphene is identified by its single-layer structure, whereas the defining clue for a fullerene is a hollow carbon shape.

Recognise the carbon structure

Turn a diagram or description into an identification by following the clues.

Predict from the description

Commit to the structure before revealing the answer.

A carbon molecule is hollow, cylindrical and much longer than its diameter. What is it?

Reason from structure to use

Problem

A diagram shows a cylindrical fullerene with a very high length to diameter ratio. Identify the structure and connect it to its uses.

Key points

1Graphene is one layer of graphite.
2Graphene is useful in electronics and composites.
3Fullerenes are hollow carbon molecules based on rings.
4C60 is a spherical fullerene.
5Carbon nanotubes are cylindrical fullerenes used in nanotechnology, electronics and materials.

Worked example

Problem

A carbon structure is hollow, cylindrical and has a very high length to diameter ratio. Identify it and give one use area.

🧠

Memory hook

Sheet, sphere, tube: graphene is the single layer; C60 is spherical; nanotubes are long cylinders.

⚠ Watch out
