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. 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) The researchers prepared magnesium intercalated C60 bulk crystals as the precursor to the exfoliation reaction. They then utilized a ligand-assisted cation exchange strategy...
