%X sp2杂化是碳碳成键的重要方式之一，利用其三重对称空间构型可以得到稳定的石墨结构和亚稳定的富勒烯、纳米碳管、石墨烯等碳纳米结构；未参与杂化的电子形成游离的π键，使得以上材料具有较好的电子导电性或其他独特的电学性质.因其优异的物理、化学、生物等特性，sp2杂化碳材料，尤其是sp2杂化纳米碳材料引起了巨大关注，有望在电子、能源、生物医疗、制药、功能材料等领域得到广泛应用.在已经进行的众多研究中，经常需要把上述碳纳米材料进行组装、构建成三维材料，从而在更大的尺度和空间中体现纳米基元的优异特性.本文综述了基于sp2杂化的三维碳材料的最新进展，以构建方式和构建基元之间的相互作用为出发点进行相关评述.</br>Abstract：sp2 hybridization is one of the most important forms of carbon-carbon bondings, and the threefold symmetry related to the bonding has led to the formation of stable graphite structure and meso-stable structures of fullerenes, carbon nanotubes and graphene. The electrons that are not involved in the hybridization form π bonds with good electric conductivity and other unique electronic properties especially in carbon nanostructures. With exotic physical, chemical and biological properties, sp2 hybridized carbon nanomaterials have attracted great attention and are expected to be applied in the fields of electronics, energy, biomedical, pharmaceutical, functional materials, etc. In the present many studies, the above-mentioned nanomaterials often need to be constructed into three-dimensional materials so as to exhibit the superior characteristics of the nanomaterials on a larger scale. This paper presents a review of the recent advances in three-dimensional materials based on sp2 hybridized carbons, and give comments on the interaction between the building blocks and factors involved in the construction.
