low, positive potentials, it would be expected that reduction of
both of these monomers must require quite negative po-
tentials, presumably a consequence of the greater elec-
tron-donating nature of the dimethylbiimidazole center.
Indeed, we were unable to observe these processes in our ex-
periments.

Atomic force microscopy
1
Atomic force microscopy (AFM) was used to investigate
the topography of poly-6 and poly-7 films deposited onto
ITO-coated glass electrodes (Fig. 5). These films appeared
smooth to the naked eye. The 25 mm  25 mm images of
poly-6 show a fairly homogeneous polymer surface, with
polymer particles of roughly 1 mm diameter distributed on
the electrode surfaces. Note that the vertical scale in this im-
age is roughly one-tenth the x- and y-axis scales. The poly-7
surface looks smooth in most areas, but also shows regions
where larger grains have deposited, of approximately 1 mm
diameter, on average.

Two novel thiophene–imidazole structures have been syn-
thesized, and their electrochemical and electronic properties
were investigated. Polymer films of 5,5’-bis(2,2’-bithio-
phene-5-yl)-1,1’-dimethyl-2,2’-biimidazole and 5,5’-bis(3,4-
ethylenedioxythiophene-2-yl)-1,1’-dimethyl-2,2’-biimidazole
were grown on platinum and indium-tin oxide-coated glass
through electrochemical polymerization. The films deposited
were fairly homogeneous, as indicated by AFM studies. The
facile polymerization of these materials and the potential to
