Abstract

Provided are graphene nanoribbons (GNRs), methods of making GNRs, and uses of the GNRs. The methods can provide control over GNR parameters such as, for example, length, width, and edge composition (e.g., edge functional groups). The methods are based on a metal catalyzed cycloaddition reaction at the carbon-carbon triple bonds of a poly(phenylene ethynylene) polymer. The GNRs can be used in devices such a microelectronic devices.
