Functionalizing Arrays of Transferred Monolayer Graphene on Insulating Surfaces by Bipolar Electrochemistry.
TLDR
Bipolar electrochemistry is used as a wireless functionalization method to graft 4-bromobenzenediazonium on large monolayer graphene sheets supported on SiO2 to show that transferred graphene can be electrochemically functionalized without the need of a metal support or the deposition of physical contacts.

One-Step Dipping Method for Covalently Grafting Polymer Films onto a Si Surface from Aqueous Media.
TLDR
A facile and one-pot dipping method was proposed in this article for the first time to prepare vinylic polymer films on a silicon (Si) surface and revealed that both polymers of poorly water soluble methyl methacrylate (MMA) and water-soluble acrylic acid (AA) monomers were covalently grafted onto the Si surface via this simple process.
Gold-organic thin films from the reductive grafting of diazonium gold(III) salts
Electrophilic radical coupling at the edge of graphene.
TLDR
For the first time, the chemical state of a single line of carbon atoms is influenced and monitored using an electrochemical cell, therefore bypassing the usual requirements of atomic resolution characterization techniques, which often demand very clean graphene samples and vacuum processing.

Grafting and properties of a porous poly(methyl methacrylate) film on a silicon surface by a one-step dipping method
In this study, we prepared a porous poly(methyl methacrylate) (PMMA) film on an Si surface with a novel dipping method. We conducted the process by directly dipping the Si substrate into acidic…

Characterization of the deposition of organic molecules at the surface of gold by the electrochemical reduction of aryldiazonium cations.
TLDR
The deposition of 4-X phenyl groups on polycrystalline gold electrode was achieved by the electrochemical reduction of the corresponding 4-substituted phenyldiazonium tetrafluoroborate salts in anhydrous acetonitrile media and showed that the formation of multilayers is possible and that a significant fraction of the deposited material remained at the electrode surface, even following ultrasonic treatment.

TLDR
It is shown that a tertiary alkyl bromide can be introduced at a given surface density to serve as radical initiator for surface-initiated atom transfer radical polymerization (SI-ATRP).

Electrochemical and atomic force microscopy study of carbon surface modification via diazonium reduction in aqueous and acetonitrile solutions.
TLDR
Lower limiting film thicknesses and surface coverages for films prepared in aqueous conditions is attributed to growth of inherently more blocking films and is supported by examination of the response of the Fe(CN)6(3-/4-) couple at NP-modified surfaces.

Raman spectroscopic determination of the structure and orientation of organic monolayers chemisorbed on carbon electrode surfaces.
TLDR
Observation of depolarization ratios for 4-nitroazobenzene and DNPH on graphite edge plane indicate that NAB is able to rotate about the NAB/carbon C-C bond, while chemisorbed DNPH is not, and the partial multiple bond character of the DNPH linkage to graphite is consistent with the observation that theDNPH π system remains parallel to the graphitic planes.
Spatially resolved spontaneous reactivity of diazonium salt on edge and basal plane of graphene without surfactant and its doping effect.
TLDR
The successful spectroscopic elucidation of the different bonding characters of 4-BBDT depending on the site of graphene is beneficial for the fundamental studies about the charge transfer phenomena of graphene as well as for the potential applications, such as electronic devices, hybridized composite structures, etc.
