Graphene derivatives containing covalently bound halogens (graphene halides) represent promising two-dimensional systems having interesting physical and chemical properties. The attachment of halogen atoms to sp(2) carbons changes the hybridization state to sp(3), which has a principal impact on electronic properties and local structure of the material. The fully fluorinated graphene derivative, fluorographene (graphene fluoride, C1F1), is the thinnest insulator and the only stable stoichiometric graphene halide (C1X1). In this review, we discuss structural properties, syntheses, chemistry, stabilities, and electronic properties of fluorographene and other partially fluorinated, chlorinated, and brominated graphenes. Remarkable optical, mechanical, vibrational, thermodynamic, and conductivity properties of graphene halides are also explored as well as the properties of rare structures including multilayered fluorinated graphenes, iodine-doped graphene, and mixed graphene halides. Finally, patterned halogenation is presented as an interesting approach for generating materials with applications in the field of graphene-based electronic devices.
含共价键卤素的石墨烯衍生物（石墨烯卤化物）代表了具有有趣物理和化学性质的有前途的二维体系。卤素原子与 sp(2) 碳原子的连接将杂化状态改变为 sp(3)，这对材料的电子性质和局部结构有主要影响。完全氟化的石墨烯衍生物，氟化石墨烯（石墨烯氟化物，C1F1），是最薄的绝缘体，也是唯一稳定的化学计量比的石墨烯卤化物（C1X1）。在这篇综述中，我们讨论了氟化石墨烯和其他部分氟化、氯化和溴化石墨烯的结构性质、合成、化学、稳定性和电子性质。还探讨了石墨烯卤化物的显著光学、机械、振动、热力学和导电性特性，以及包括多层氟化石墨烯、碘掺杂石墨烯和混合石墨烯卤化物在内的稀有结构的特性。最后，提出了图案化卤化作为一种有趣的方法，用于生成应用于基于石墨烯的电子器件领域的材料。
