Ferrocene‐functionalized disubstituted polyacetylenes are synthesized in high yields by copper‐catalyzed click reactions of azido‐decorated poly(1‐phenyl‐1‐hexyne) and poly(diphenylacetylene) with 1‐ethynylferrocene. All the organometallic polymers are soluble and film‐forming. They enjoy high thermal stability (≥300 °C) and are redox‐active. Thanks to the ferrocenyl units, thin films of the polymers show high refractive indices ( n =1.745–1.698) in the wavelength region of 400–1700 nm as well as high Abbé numbers ( v D ’ up to 426) and low optical dispersions ( D ’ down to 0.002) at telecommunication important wavelengths. Pyrolyses of the polymers under nitrogen furnish magnetic ceramics with high magnetizabilities.
