Self-assembly pre-occupancy for 2D super-ordered emptiness arrays in graphene

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.
