We studied chemical doping of trans- and cis-azobenzene on graphene by Raman spectroscopy. It was found that the molecule induces hole-doping in graphene through charge transfer. Moreover, the doping level in graphene can be reversibly modulated by a photocontrolled molecular conformation change. As...
