Synthesis of 1,4-bis(p-aryloxy-tetrafluorophenyl)butadiyne monomers for nonlinear optics
摘要:
Novel diacetylenes with polyfluorophenyl groups directly bound to the diacetylene moiety, 1,4-bis(p-aryloxy-tetrafluorophenyl)butadiynes, were prepared in four steps from pentafluoroiodobenzene and trimethylsilylacetylene.
