Bottom-up synthesis of quasi-one-dimensional graphene nanoribbons (GNRs) with defined structures and controllable properties has attracted great attention for potential applications in electronic and optoelectronic devices. Here we report a new on-surface method for high-throughput synthesis of GNRs without the need to sublime the precursors, but through solution processing. The new method is far simpler and more scalable compared to the previous GNR syntheses based on chemical vapor deposition or (ultra)high vacuum conditions, while preserving the high quality and uniformity as determined by Raman spectroscopy.
