Doping and its consequences on the electronic features, optoelectronic features, and magnetism of graphynes (GYs) are reviewed in this work. First, synthetic strategies that consider numerous chemically and dimensionally different structures are discussed. Simultaneous or subsequent doping with heteroatoms, controlling dimensions, applying strain, and applying external electric fields can serve as effective ways to modulate the band structure of these new sp2/sp allotropes of carbon. The fundamental band gap is crucially dependent on morphology, with low dimensional GYs displaying a broader band gap than their bulk counterparts. Accurately chosen precursors and synthesis conditions ensure complete control of the morphological, electronic, and physicochemical properties of resulting GY sheets as well as the distribution of dopants deposited on GY surfaces. The uniform and quantitative inclusion of non-metallic (B, Cl, N, O, or P) and metallic (Fe, Co, or Ni) elements into graphyne derivatives were theoretically and experimentally studied, which improved their electronic and magnetic properties as row systems or in heterojunction. The effect of heteroatoms associated with metallic impurities on the magnetic properties of GYs was investigated. Finally, the flexibility of doped GYs’ electronic and magnetic features recommends them for new electronic and optoelectronic applications.

The emergence of a two‐dimensional (2D) functionalized‐graphene structure, graphdiyne (GDY), promoting non‐metallic single atoms level to tailor its gas sensing performance. Herein, pristine, non‐metallic atom (N, B) doped 2D GDY is investigated for toxic and greenhouse gases sensing (CO, CO2, CH4, HCHO, H2S, SO2, SO3, NO2, NO, and NH3). The B‐doped GDY (B‐GDY) compared with pure or N doped GDY displays gas sensitivity, especially excellent sensitivity and selectivity toward NO, NO2, and NH3. Additionally, a humid environment has demonstrated no effect on the weakening selectivity of B‐GDY for the studied gases. Meanwhile, the effect of external electric field (E‐field) on sensing was calculated, indicating that the bandgap of NO‐adsorbed system reached the lowest 0.188 eV at −0.5 V Å−1 and the highest 0.363 eV at −0.1 V Å−1. This work paves the way on designing efficient and effective gas sensor toward toxic nitrogen‐based gases on GDY.

“…As a semiconductor material [120,121], GDY has a natural and direct band gap of 0.52 eV (Figure 12a) [28,122]. This band gap can be reduced to 0.26 eV (Figure 12b) by the anchoring of Ni atoms on the surface of GDY [123], which effectively improves the conductivity and further accelerates the electrocatalytic reaction.…”

Graphdiyne (GDY) is a two-dimensional (2D) electron-rich full-carbon planar material composed of sp2- and sp-hybridized carbon atoms, which features highly conjugated structures, uniformly distributed pores, tunable electronic characteristics and high specific surface areas. The synthesis strategy of GDY by facile coupling reactions under mild conditions provides more convenience for the functional modification of GDY and offers opportunities for realizing the special preparation of GDY according to the desired structure and unique properties. These structural characteristics and excellent physical and chemical properties of GDY have attracted increasing attention in the field of electrocatalysis. Herein, the research progress in the synthesis of atomic-level functionalized GDYs and their electrocatalytic applications are summarized. Special attention was paid to the research progress of metal-atom-anchored and nonmetallic-atom-doped GDYs for applications in the oxygen reduction reaction (ORR), the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) catalytic processes. In addition, several potential development prospects and challenges of these 2D highly conjugated electron-rich full-carbon materials in the field of electrocatalysis are presented.
