Carbon nanotubes as templates for 1D nanostructures via a one-reactant-one-pot method — •Thomas Chamberlain — University of Leeds, Leeds, UK

Harnessing functional properties which emerge at the nanoscale is the key to developing superior materials for catalytic, electronic and biomedical applications. The internal cavity of single-walled carbon nanotubes provides an effective template for control of the exact positions and orientations of molecules and atoms and has been successfully applied to the construction of nanoscale architectures from a variety of metals, organic molecules, and inorganic compounds [1-3]. Low-dimensional inorganic materials, including transition metal chalcogenides, are of particular interest as their semiconducting properties can be precisely tuned by shaping their structures into nanoribbons. While the host-nanotube can control the dimensions of the inorganic structure, the stoichiometry is much more difficult to control.

An all-in-one molecular precursor that contains all necessary elements in correct proportion for the desired product, encapsulated in SWNTs and subsequently converted into the nanomaterial offers a highly effective solution to this challenge. This new strategy for nanoribbon synthesis and characterisation at the nanoscale can enable the formation of previously inaccessible quasi one-dimensional nanomaterials suitable for a variety of technological applications.
