A new method for measuring infrared spectra of a Ti(O-n-Bu)4-AlEt3 catalyst is developed. Upon heat treatment of the catalyst, formation of linear and/or cyclic oxo-complexes of titanium having the Ti-OTi linkage is suggested. The existence of oxo-complexes seems to be correlated with high electrical conductivity of resulting polyacetylene upon full iodine-doping. Raman spectra arising from doped domains have been obtained for the first time by Fourier transform Raman spectroscopy with 1064-nm excitation. Even at full iodine-doping, the polymer chain does not have a uniform bond order, and contains dope domains in which bond alternation persists. Small differences are observed between the Raman spectra of conventional and new highly-conducting polyacetylenes.
