1,4-diiodo-1,3-butadiyne and 1-iodo-1,3,5-hexatriyne were polymerized in the siliceous MCM-41 mesoporous molecular sieve to prepare carbonaceous material with oligoyne segments. Polymeric carbon, confined in the channels, showed a broad IR band at 2090-2180 cm-1 corresponding to conjugated sp-bonded carbons. Both the precursors and the polymerization products showed improved chemical and thermal stability if they were confined inside the MCM-41 matrix.
