Organometallic Complexes of Graphene
Santanu Sarkar, Sandip Niyogi, Elena Bekyarova +1
We demonstrate the organometallic hexahapto complexation of chromium with graphene, graphite and carbon nanotubes. All of these extended periodic pi-electron systems exhibit some d…
Electrochemical Grafting of Naphthylmethyl Radicals to Epitaxial Graphene: A Versatile Platform to Reversibly Engineer the Band Structure and Transport Properties of Graphene
Santanu Sarkar, Elena Bekyarova, Robert C. Haddon
The Kolbe electrochemical oxidation strategy has been utilized to achieve an efficient quasireversible electrochemical grafting of the alpha-naphthylmethyl functional group to grap…
Organometallic Hexahapto Functionalization of Single Layer Graphene as a Route to High Mobility Graphene Devices
Santanu Sarkar, Hang Zhang, Jhao-Wun Huang +4
Organometallic hexahapto chromium metal complexation of single layer graphene, which involves constructive rehybridization of the graphene pi-system with the vacant chromium d orbi…
Aryl Functionalization as a Route to Band Gap Engineering in Single Layer Graphene Devices
Hang Zhang, Elena Bekyarova, Jhao-Wun Huang +5
Chemical functionalization is a promising route to band gap engineering of graphene. We chemically grafted nitrophenyl groups onto exfoliated single-layer graphene sheets in the fo…
