A new class of conducting polymers, 3,3'-dialkyl-2,2'-dithiophene-5,5'
-diylvinylene)s, have been prepared from dialkyl substituted E-(2,2'-d
ithienylethylene). Soluble materials bearing long alkyl chains have be
en obtained by either chemical or electrochemical synthesis. These con
jugated polymers were characterized by NMR, FTIR and UV-visible-NIR sp
ectroscopy.
