Abstract

The controlled ring-opening metathesis polymerization of 7, 8-bis(trifluoromethyl)tricyclo[4.2.2.0^{2, 5}]- deca-3, 7, 9-triene has been employed to prepare soluble polymers of low polydispersity that are precursors to polyenes. Films of these precursor polymers have been cast from solution onto platinum microelectrode arrays and have been heated to form films of polyacetylene in the molecular weight range 400-6500. These films have been characterized by in situ measurements of conductivity as a function of electrochemical potential in liquid SO₂/electrolyte. The results show a steady increase in conductivity with average chain length for samples with chain lengths in the range 11-60 double bonds, above which conductivity levels off as chain length continues to increase. All samples exhibit a finite potential window of conductivity which increases in width in the range 11-60 double bonds and does not change further with increasing chain length.
