“…Figure a depicts the reaction mechanism of GDY sheets by using HEB as the monomer. Catalysis of Cu was uniformly pregrown on the substrate by the PVD method, and the coupling reactions of HEB occurred in pyridine solution. , The synthesized GDY sheets then gradually grew on the substrate and formed well-proportioned nanofilm (Figure b). By carefully adjusting the PVD procedure conditions, nano-Cu could be deposited on various substrates and allowed us to grow a uniform GDY film on different materials (Figure S2).…”

Like the multilayered graphene which is the most widely used solid lubricant, graphdiyne (GDY) as a 2D material holds potential similar prospects but has been rarely researched so far. One reason is that growing a GDY film in a controllable manner on diverse material surfaces remains a great challenge. To address the issue, a catalytic pregrowth and solution polymerization method is developed to synthesize a GDY film on various substrates. It allows fine control over film structure and thickness. A macroscopic ultralow friction coefficient of 0.08 is obtained, and a relatively long life of more than 5 h under a high load of 1378 MPa is achieved. Molecular dynamics simulations together with the surface analysis demonstrate that the increased deformation degree and weakened relative motion between GDY layers contribute to the low friction. Especially, different from graphene, the friction of GDY exhibits a double increase and decrease in one period of λ ≈ 8–9 Å, and it is roughly equal to the distance between two adjacent alkyne bonds in the x direction, indicating GDY’s structure and lattice play an important role in reducing friction.

“…Despite the outstanding merits of the interface synthesis, this method greatly suffers from the long-time reaction period and the uncontrollable side reactions. Very recently, Zhang and coworkers 38 launched a rapid and controllable synthesis of GDY films by efficient Cu(II)-N,N,N 0 ,N 0 -tetramethylethylenediamine (Cu(II)-TMEDA) catalyst through a super spreading liquid/liquid interface on a hydrogel (Figure 5D). Out of the nucleation and in-plane extension processes, the GDY film with tunable thickness (4 $ 50 nm) and large-scale 2D morphology can be formed within 2 h at room temperature.…”

Graphdiyne (GDY), an emerging two‐dimensional all‐carbon allotrope, features the coexistence of sp and sp2 hybridized planar carbon atoms. GDY and GDY‐based materials exhibit unique physical and chemical properties, such as well‐defined molecular skeleton, π‐conjugated structure, high specific surface area with porosity, and good electrical conductivity, which have aroused widespread interest in various disciplines. As an emerging field, in this work, we summarize important synthesis strategies of GDY and GDY‐based materials including classical synthesis, chemical vapor deposition, explosion approach, and interface‐assisted methods. We also elaborate the recent modifications to regulate the structure and properties of GDY from the viewpoint of metal doping, non‐metal doping, and heterostructure construction. Meanwhile, recent achievements and progress in the development of energy and environmental applications in photocatalysis are highlighted. Lastly, the challenges and potential developments of GDY in the catalytic research are given at the end of this article.

Dynamical performance of multilayer graphdiyne (MLGDY) with ultra‐low density and flexible features is investigated using laser‐induced micro‐projectile impact testing (LIPIT) and molecular dynamics (MD) simulations. The results reveal that the MLGDY exhibits excellent dynamic energy dissipation ability mainly due to the excellent in‐plane wave velocity resulting from the diacetylene linkages between benzene rings. In addition, the unique multiple crack tips and their propagation further promote the energy dissipation capability. The energy dissipation capability of the MLGDY is found to reduce with increasing thickness due to compression‐shear induced failure of several upper layers of relatively thick MLGDY, which hinders delocalized energy dissipation ability. Moreover, the impact resistance force of the MLGDY increases almost linearly with increasing impact velocity, demonstrating the applicability of the traditional compressive resistance theory of laminates for MLGDY. Based on the experimental observation and the simulation results, two feasible strategies, i.e., combining with high‐strength multi‐layer graphene and rotated graphdiyne (GDY) interlayer to avoid stacking of sp‐hybridized carbon atoms, are proposed to further improve the impact resistance of the MLGDY. The study provides direct proof of excellent impact resistance of the versatile MLGDY and proposes feasible fabrication strategies to further improve the anti‐ballistic performance in future.
