Electrochemical grafting assisted modification of graphite surface by 3,4,5-trimethoxybenzenediazonium based monolayer

A conventional route to create such nanoscale electronic devices using the autonomous ordering and assembly of organic molecules on atomically well-defined surfaces has been proposed. However, these thin films are unstable in realistic environments due weak interaction between crystal surfaces. Therefore, enhancing interfacial them is assigned as key approach extend scope application promising monolayer films. In this work, we demonstrate formation an monolayer, namely 3,4,5-trimethoxy diazonium (3,4,5-TMD), a Highly Ordered Pyrolytic Graphite (HOPG) electrode by power electrochemical method. The structural properties at nano scale well bonding nature 3,4,5-TMD adlayer HOPG interface were investigated combination cyclic voltammetry (CV), atomic force spectroscopy (AFM) Raman spectroscopy. As result, covalently bond carbon atoms located for forming with its thickness 0.92 ± 0.02 nm. This finding opens partway apply grafting covalent functionalization 2D materials other metallic
