Keys to conducting polymer applications:
     Synthetic control and processibility
Examples:
a) Regioregular poly(3-hexyl
thiophene) or  r-P3HT
b) Poly(2-methoxy-5-(2'-ethylhexoxy)-
phenylene vinylene) or 2MehPPV
c) Polyaniline dodecylbenzene
sulfonate or DBSA-PANI
Ø Competing interactions and chemical incompatibilities
(i.e. polar vs. nonpolar) has given rise to new
structure/property relationships.
