We have demonstrated a methodology to generate large area graphdiyne films with 3.61 cm² on the surface of copper via a cross-coupling reaction using hexaethynylbenzene. The device based on graphdiyne films for measurement of electrical property is fabricated and shows conductivity of 2.516 × 10^-4 S m^-1 indicating a semiconductor property.
