▎ 摘 要
The benzyne functionalization of chemical vapor deposition grown large area graphene and graphite was performed using a mixture of o-trimethylsilylphenyl triflate and cesium fluoride that react with the carbon surface. The reaction requires at least 2 days of treatment before the appearance of Raman and energy-dispersive X-ray spectral signatures that verify modification. Raman spectra of modified graphene and graphite show a rich structure oflines corresponding to C=C-C, C-H, and low frequency modes of surface-attached benzyne rings. (c) 2012 Elsevier Ltd.
