Synthesis of asymmetric polyfluoro-diacetylene monomers
摘要:
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.
