摘要: We present a versatile and simple method using electrochemistry for the exclusive functionalization of edge graphene monolayer with metal nanoparticles or polymeric amino groups. The attachment allows us to exploit surface-enhanced Raman scattering characterize chemistry both pristine functionalized edge. For patterned edge, we observe typical edge-related modes, while identify chemical structure functional layer by vibrational fingerprinting. ability obtain single selectively edges routinely on an insulating substrate opens avenue exploring effect properties systematically.
