Asymmetric diacetylene monomers with polyfluoro-aromatic rings for nonlinear optics were prepared by the cross coupling of 1-bromo-acetylenes with polyfluoro-aromatic acetylenes which were prepared by nucleophilic substitution on pentafluorophenyltrimethylsilylacetylene.

Substitutions on trimethylsilylsilane (1) with nucleophiles, Nu-X (2) give the corresponding trimethylsilanes (3) or (p-substituted-tetrafluorophenyl)ethynes (4).The trimethylsilyl group of (3) can be easily removed by treatment with dilute alkali to give (p-substituted-tetrafluorophenyl)-ethynes (4).Diacetylenes containing fluoro-aromatic rings are prepared by the Chodkiewiez-Cadiot and the Hay coupling of the corresponding terminal acetylenes (4).
