摘要
Abstract Currently, studies on organic two-dimensional (2D) materials with special optic-electronic properties are attracting great research interest. However, 2D organic systems possessing promising electrical transport properties are still rare. Here a highly crystalline thin film of a copper coordination polymer, Cu-BHT (BHT=benzenehexathiol), is prepared via a liquid–liquid interface reaction between BHT/dichloromethane and copper(II) nitrate/H 2 O. The morphology and structure characterization reveal that this film is piled up by nanosheets of 2D lattice of [Cu 3 (C 6 S 6 )] n , which is further verified by quantum simulation. Four-probe measurements show that the room temperature conductivity of this material can reach up to 1,580 S cm −1 , which is the highest value ever reported for coordination polymers. Meanwhile, it displays ambipolar charge transport behaviour and extremely high electron and hole mobilities (99 cm 2 V −1 s −1 for holes and 116 cm 2 V −1 s −1 for electrons) under field-effect modulation.
