Three symmetrical dipyridyloctatetrayne monomers, i. e., 1,8-di(x-pyridyl)octatetrayne: x=2, 3 and 4, were synthesized and their solid-state polymerization was investigated. In addition, a salt prepared from 1,8-di(3-pyridyl)octatetrayne and p-nitrobenzoic acid was found to be polymerized via 1,4- addition in the solid state.
