The present invention generally relates to nanostructure compositions, as well as methods for the controlled synthesis of nanostructures, such as carbon nanotubes. In some embodiments, methods involving iterative growth of a nanostructure template to homogeneously produce nanostructure compositions are provided. The compositions may include nanostructures having a specific length, width, diameter, ring orientation, and/or other characteristics. Using methods described herein, nanostructures (e.g., nanotubes) having uniform properties, such as electrical conductivity, may be readily produced. The ability to provide homogeneous nanostructure compositions may be advantageous in the design and fabrication of numerous materials and electronic devices.

The controlled chemical synthesis of uniform, single‐walled carbonnanotubes from short hydrocarbon templates, such as aromatic belts and geodesic nanotube end‐caps, by a Diels–Alder cycloaddition/rearomatization strategy requires a potent “masked acetylene” capable of transforming hydrocarbonbayregions into new unsubstitutedbenzenerings in a single operation. Nitroethylene has been found to effect
