Abstract Diiodoacetylene was electropolymerized with Pt cathode at −2.0 V (vs. SCE) in the presence of Ni complex in dimethylformamide (DMF) under anaerobic conditions, giving an insoluble black powder which had a strong infrared absorption at 2050 cm−1 and a broad Raman peak around 2150 cm−1 due to conjugated polyyne structure. A compressed pellet of the as-prepared sample had an electrical conductivity of 3 × 10−5 S cm−1.
