On-surface Synthesis of Graphene Clusters from a Quaterphenyl-branched Z-bar-linkage Precursor

摘要

Graphene nanoribbons (GNRs), narrow strips of graphene, show intriguing properties dependent on their widths, edge structures, etc. Bottom-up approach enable atomically precise control over the GNRs structures. Two-zone chemical vapor deposition (2Z-CVD) with independent temperature control in two contiguous zones proved high output in the bottom-up synthesis of GNRs with atomical precision.
