In this Hot Communication, the team from Chubu University, Japan, demonstrate a simple synthesis of an iodine-doped graphene film using a mixture of camphor and iodine. Experiments confirm the presence of atomic iodine in the form of triiodide (I⁻₃) and pentaiodide (I⁻₅) through charge transfer reactions. The sp² hybridized carbon in graphene is not disturbed by the presence of atomic iodine. The team say that the atomic iodine could be situated on the surface or as an intercalation in the form of polyiodides without disturbing the hexagonal lattice structure of the few-layers graphene film.
