Synthesis of the title compound, 15-(5,10-dimethylcyclotrideca-2,4,10,12-tetraene-6,8-diynylidene)-6,11-dimethylcyclopentadeca-1,3,5,11,13-pentaene-7,9-diyne, is described. Examination of 1H and 13C NMR spectra indicated that the tridecapentadecafulvalene derivative shows no ring-current effect but did have polyolefinic character.
