The reaction of dilithiobutadiyne (or the corresponding di-Grignard reagent) with various dichlorosilanes and dibromogermanes in THF at room temperature afforded poly[(silylene)diacetylenes] and poly[(germylene)diacetylenes], respectively, in high yields. The polymers have a regular alternating arrangement of diyne and silylene or germylene units. When they are doped with FeCl3, these polymers show conductivity values in the range 10-5-10-3 S·cm-1. The values depend greatly on the electronic character of the substituents bonded to silicon or germanium.
