Metal Delivery

Contact electrochemical transfer of silver from a metal-film stamp (parallel process) or a metal-coated scanning probe (serial process) is demonstrated to allow site-selective metallization of monolayer template patterns of any desired shape and size created by constructive nanolithography. The precise nanoscale control of metal delivery to predefined surface sites, achieved as a result of the selective affinity of the monolayer template for electrochemically generated metal ions, provides a versatile synthetic tool en route to the bottom-up assembly of electric nanocircuits. These findings offer direct experimental support to the view that, in electrochemical metal deposition, charge is carried across the electrode–solution interface by ion migration to the electrode rather than by electron transfer to hydrated ions in solution.

The quest for planar sp2-hybridized carbon allotropes other than graphene, such as graphenylene and biphenylene networks, has stimulated substantial research efforts because of the materials’ predicted mechanical, electronic, and transport properties. However, their syntheses remain challenging given the lack of reliable protocols for generating nonhexagonal rings during the in-plane tiling of carbon atoms. We report the bottom-up growth of an ultraflat biphenylene network with periodically arranged four-, six-, and eight-membered rings of sp2-hybridized carbon atoms through an on-surface interpolymer dehydrofluorination (HF-zipping) reaction. The characterization of this biphenylene network by scanning probe methods reveals that it is metallic rather than a dielectric. We expect the interpolymer HF-zipping method to complement the toolbox for the synthesis of other nonbenzenoid carbon allotropes.

The quest for planar sp2-hybridized carbon allotropes other than graphene, such as graphenylene and biphenylene sheet, has stimulated substantial research efforts because of the materials' predicted unique mechanical, electronic and transport properties. However, their synthesis remains challenging due to the lack of reliable protocols for generating non-hexagonal rings during the in-plane tiling of carbon atoms. Here, we report the bottom-up growth of ultra-flat biphenylene sheet with periodically arranged four-, six-, and eight-membered rings of sp2 carbon atoms, via an unprecedented on-surface inter-polymer hydrogen fluoride (HF)-zipping reaction. The characterization of this biphenylene sheet by scanning probe methods solves the long-standing controversy over its dielectric or metallic nature. We expect the inter-polymer HF-zipping method to complement the toolbox for the synthesis of other nonbenzenoid carbon allotropes.
