Background/unmet need

Graphene nanoribbons (GNRs) possess compelling properties that have made them a highly promising candidate for next-generation electronic materials. Specifically, GNRs have a non-zero bandgap that can be tuned by both their width and edge structures. However, controlled synthesis of GNRs with precise length and edge structures remains challenging.

Invention Description

Researchers at UT Austin have described new synthetic methods to obtain new small nanographenes and long graphene nanoribbons (GNRs). These methods have the notable advantage of explicit control over the width and terminal-edge structures of the GNRs. This bottom-up approach is modular by design, uses polymer precursors that can be efficiently synthesized from commercially available small molecules, and holds potential for rapid access to other GNRs. In brief, the features of this new synthetic approach allow step- and cost-savings in the production of GNRs. 

Benefits/Advantages

  • Rapid synthetic routes to nanographenes (including their single crystals) and GNRs by use of a novel monomer
  • A step- and cost-saving, modular approach

Features

  • Unambiguous control over width and terminal-edge structures 
  • Potential for easy access to other GNRs with different width and edge functions
