One-dimensional nanostructures of the organic charge-transfer (CT) complex CuTNAP (copper 11,11,12,12-tetracyano-2,6-naphthoquinodimethane) were successfully synthesized by an organic vapor–solid phase reaction. The morphologies and field-emission properties of the CuTNAP nanostructures can be easily tuned by controlling the reaction conditions. It was observed that the field emission property is dependent on the morphology. The current density of a CuTNAP film of nanowires reaches up to 13.1 mA cm−2, which is the highest among the organic semiconductors, even higher than most inorganic materials. These results demonstrate that the CuTNAP complex nanostructures are excellent potential candidates as field emitters.
