polythiophene, polypyrrole, polyacetylene,
Yoshinar; Toshihiko
polyperinaphthalene, polyfuran, polyfiurane,
Nishiyama; Naoki
polythienylene, polypyridinediyl, polyindole,
Takahashi/Japan
indoletrimer compounds, polyaminoanthraquinone,
polyimidazole, quinones such as benzoquinone, and
anthraquinone where a quinone oxygen can be
converted to a hydroxyl group.

substituent such as CH 3– O-, C 2 H 5 O–, HO–, –CH 3
radicals. Salen represents residue of
bis(salicylaldehyde) ethylenediamine in Schiff’s base.
Preferences for conducting substrate include carbon
fiber, carbon materials with metal coatings, and metal
electrodes with high specific surface areas.
