The synthesis of graphynes has often been limited to using irreversible coupling reactions that are likely to result in materials that lack long-range order. Now, a periodically sp–sp
2-hybridized carbon allotrope, γ-graphyne, is prepared using a reversible dynamic alkyne metathesis and managing the balance between kinetic and thermodynamic control. This material’s interlayer stacking and folding behaviour are also revealed.
