摘　　要：Self-assembly is deemed to be an effective and inspiring strategy to construct programmable and innovative super-ordered structures.Here,we have,for the first time,achieved the large-area super-ordered two-dimensional(2D)emptiness arrays in graphene by silicon dioxide self-assembly pre-occupancy.The prominent uniform periodicity of 2D emptiness arrays in graphene can be flexibly adjusted.The synergistic interaction between the pre-occupancy structural unit and graphene contributes to the successful acquisition of 2D emptiness arrays.The realization of 2D emptiness arrays by self-assembly pre-occupancy strategy would shed light on the rational redaction,fabrication and research of complex 2D super-ordered structure systems and facilitate their applications for various fields,such as highly integrated functional devices,precise location acquisition systems,sensing,separation,and so on.自组装是一种构建可编辑和新颖的超有序结构的有效策略.在此,我们首次通过二氧化硅的自组装预占位,在石墨烯中实现了大面积超有序二维空阵列.石墨烯中的二维空阵列均匀的周期性在宽范围内可灵活调节.实验证明预占位结构单元二氧化硅与石墨烯之间的协同作用有助于二维空阵列的成功获得.超有序二维空阵列的成功实现,可为复杂二维超有序结构系统的合理编辑、制备和研究提供借鉴,并促进其在高集成功能器件、精确定位采集系统、传感、分离等领域的应用.
