Electrochemical polymerization of bis(2-thienyl)dimethylsilane (BTMS),
1,2-bis(2-thienyl)tetramethyldisilane (BTMDS), bis(2-thienyl)diphenys
ilane (BTPS), and 2,5-bis(trimethylsilyl)thiophene (BTMST) was studied
. These thiophenes bearing silyl substituents produced conducting poly
mer films which showed IR spectra, optical absorption spectra, and cyc
lic voltammograms identical to the film prepared from thiophene. Howev
er, SEM photographs showed morphological difference between the films
from the silyl-substituted thiophenes and from thiophene.
