Synthetic carbon allotropes are intriguing due to their exceptional properties and potential applications. Scientists have devoted decades to synthesizing new types of carbon materials. However, a two-dimensional fullerene, which possesses a unique structure, has not been successfully synthesized until now.
合成碳同素异形体因其卓越的特性和潜在的应用而引起人们的兴趣。 科学家们几十年来一直致力于合成新型碳材料。 然而，迄今为止尚未成功合成具有独特结构的二维富勒烯。
Recently, scientists developed a new interlayer bonding cleavage strategy to prepare a two-dimensional monolayer polymeric fullerene. The research group was led by Prof. ZHENG Jian from the Institute of Chemistry of the Chinese Academy of Sciences (ICCAS) .
最近，科学家们开发了一种新的层间键裂解策略来制备二维单层聚合富勒烯。 课题组由中科院化学所郑健教授领导。
The researchers prepared magnesium intercalated C60 bulk crystals as the precursor to the exfoliation reaction. They then utilized a ligand-assisted cation exchange strategy to cleave the interlayer bonds into bulk crystals, which led to the bulk crystals being exfoliated into monolayer nanosheets.
研究人员制备了镁插层 C60 块状晶体作为剥离反应的前体。 然后他们利用配体辅助的阳离子交换策略将层间键切割成块状晶体，这导致块状晶体剥落成单层纳米片。
The structure of monolayer polymeric C60 was explored by single crystal X-ray diffraction and scanning transmission electron microscopy (STEM). In this monolayer polymeric C60, cluster cages of C60 are covalently bonded with each other in a plane, forming a regular topology that is distinct from that of conventional 2D materials.
通过单晶 X 射线衍射和扫描透射电子显微镜 (STEM) 探索了单层聚合物 C60 的结构。 在这种单层聚合物 C60 中，C60 的簇笼在平面内相互共价键合，形成不同于传统二维材料的规则拓扑结构。
Furthermore, the monolayer polymeric C60 exhibits an interesting in-plane anisotropic property and a moderate bandgap of 1.6 eV, which makes it a potential candidate for use in electronic devices.
此外，单层聚合物 C60 表现出有趣的面内各向异性特性和 1.6 eV 的适中带隙，使其成为电子器件的潜在候选者。
“The work is the first to synthesize a monolayer polymeric fullerene. It is of great significance, as it adds a new member to the carbon material family,” ZHENG said. “This work has opened up a new research field in two-dimensional carbon material areas and the synthesis strategy could provide a unique perspective in exploring new carbon material.”
“这是一项第一个合成单层聚合富勒烯的工作；意义重大，因为它为碳材料家族增加了一个新成员，“郑说。 “这项工作开辟了二维碳材料的新研究领域，合成策略可以为探索新型碳材料提供独特的视角。”
