Abstract

original image

A new polymer with C4H stoichiometry based on graphene is synthesized in situ using template-induced polymerization of self-organizing hydrogen adsorbates on graphene. The polymerization is observed “live” on the surface of graphene by photoemission spectroscopy. Photoemission spectroscopy allows for an accurate determination of the carbon/hydrogen stoichiometry, an aspect that is extremely important for understanding functionalized graphene.
