Abstract:
We present a new strategy to grow high-quality graphene by physical vapour deposition (PVD) using as precursor C60 molecules evaporated in ultra high vacuum conditions (UHV). A multitechnique characterization was performed to determine…

High yielding and extremely site-selective covalent functionalization of graphene

High yielding and extremely site-selective covalent functionalization of graphene

Author: 

Chem. Commun., 2017.

Abstract:

We describe a method to functionalize graphene covalently with 92% yield and 98% site-selectivity and strict spatial periodicity on the nanometer scale. This method could be extended to other functional molecules…
