Product Overview
Graphdiyne (GDY) is a new type of carbon nanostructure material, which becomes an important member of the carbon material family after fullerenes, carbon nanotubes, and graphene. Graphdiyne has unique structure and excellent performance. Its structure contains rich carbon-carbon bonds and holes, has sp and sp2 hybridization states, and rich carbon chemical bonds, large conjugated system, wide interlayer spacing, and excellent chemical stability, which gives it good conductivity, optical properties, and chemical stability. Graphdiyne has excellent semiconductor properties, similar to the semiconductor properties of silicon, and its special molecular structure and electronic structure not only have electron-donating properties, but also have electron-withdrawing properties. The synthesis method of graphdiyne is mainly chemical methods, such as successfully synthesizing large-area graphdiyne thin films on copper foil by using hexacarbonylbenzene under the catalytic action of copper foil. During this process, the copper foil not only acts as a catalyst for the cross-coupling reaction, growth substrate, but also provides a large planar substrate for the directed polymerization of the graphdiyne thin film.

Product Features
Structural Features: It has sp and sp2 hybridization states, as well as rich carbon chemical bonds, a large conjugated system, a wide interlayer spacing, and excellent chemical stability.
Physical Properties: The interlayer spacing of graphyn is 0.365 nanometers. Theoretically, as the thickness of graphyn decreases, its electrical conductivity gradually increases.
Chemical Properties: Graphyn has excellent semiconductor properties, similar to the semiconductor properties of silicon, and its special molecular structure and electronic structure not only have electron-donating properties but also have electron-withdrawing properties.
Application Fields
Electronic and semiconductor fields: Graphitic acetylene is expected to be widely used in electronic and semiconductor fields due to its special electronic structure and excellent semiconductor properties. For example, graphite acetylene doping into the electron transport layer of hybrid perovskite devices can effectively improve the conductivity of the electron transport layer, and thus improve the device performance of perovskite batteries.
Energy field: Graphitite is a very ideal lithium storage material, and its unique structure is more conducive to the diffusion and transmission of lithium ions in and out of the plane, giving it a very good rate performance. The theoretical lithium storage capacity of graphitic acetylene can reach 744mAh/g, and the theoretical capacity of multilayer graphitic acetylene can reach 1117mAh/g (1589mAh/cm³). In addition, graphylene can also be used as a highly efficient cathode material for potassium-sulfur (K-S) batteries to improve the performance of the batteries.
Catalytic field: Graphylene has excellent catalytic performance, such as the supported metal palladium can efficiently catalyze the reduction of 4-nitrophenol, and the reduction rate is much higher than that of other carbon-based Pd composite nanomaterials. At the same time, graphylene can also play a role in regulating the catalytic performance of electrochemical luminescence (ECL) as a supporting substrate.
Photoelectric field: The perovskite solar cell constructed by the composite of graphite acetylene and P3HT as a modification material can significantly improve the hole transmission performance, and the photoelectric conversion efficiency of the perovskite cell based on this composite hole transport layer is increased by 20%, achieving a high efficiency of 14.58%.
Other fields: Graphylene can also be used to filter sodium chloride from seawater, as a buffer layer for quantum dot batteries, etc.
