Abstract: Graphdiyne(GDY) has the unique feature in the topological ordered arranged sp- and sp2-hybridized carbon atoms, thus deriving a series of 2D allotropes. Due to inhomogeneous π-bonding and carbon orbital overlap between different hybrid carbon atoms, GDY possesses a natural band gap with a Dirac cones structure. And GDY exhibits semiconductor property with a conductivity of 2.516×10-4 S/m at room temperature. The topological distribution of alkyne and benzene bonds of GDY makes its surface charge distribution extremely uneven, which produces high intrinsic activity for further modification. Its unique molecular structure endows the specific interaction with various species, such as ions, atoms, molecules and nanoparticles, showing excellent charge transport capability and unique advantages in mass transfer and energy conversion. From the view of the interaction principle between GDY and different compositions, we summarized the application of GDY-based materials in the fields of catalysis, energy conversion and storage, biological detection and so on.
