New synthesis method produces long and defect-free graphene nanoribbons

Researchers from the Max Planck Institute for Polymer Researcher developed a new method to produce very long and well-defined graphene nanoribbons (GNRs). The resulting defect-free ribbons are liquid-phase-processable and could enable effective transistors and other electronic devices.

The new method is a bottom-up one - synthesizing graphene ribbons from molecular building blocks. This method is a modification to the solution-mediated production method developed in 2011 by the same group.
