ELECTROCHEMICAL ISOMERIZATION OF CIS-(CH)_x TO TRANS-(CH)_x.

This study was performed in order to (i) show that isomerization can be attained by electrochemical undoing of cis-(CH)//x followed by its electrochemical undoping to parent trans-(CH)//x; (ii) confirm the electrochemical conversion of (CH)//x to the p- or n-doped metallic state by physical measurements other than electrical conductivity; and (iii) to show that electrochemical and also chemical isomerization of cis-(CH)//x to trans-(CH)//x takes place via the intermediate formation of chemically similar doped (CH)//x species.
