The allylnickel-catalyzed living coordination polymerization of allenylferrocene was compounded, two allenylferrocene derivatives (L-1 and D-1) bearing chiral amide pendants were designed and synthesized. The living coordination polymerization of L-1 and D-1 were afforded by the allynickel(II) complexes, which gave the polymer with controlled molecular weights and narrow molecular weight distribution in high yields. Three polyallenylferrocenes exhibited electrochemical properties. The helical structure was stable in the aprotic solvents observed through the circular dichroism spectra.
